Best ResponseYou've already chosen the best response.0I know you do the parenthesis first, right?

Best ResponseYou've already chosen the best response.2Yes. Distribute the 3 on the left side, and distribute the 2 on the right side. That gets rid of the parentheses on both sides. What do you get?

Best ResponseYou've already chosen the best response.2Let's do it one step at a time. We start with the original equation: dw:1433462580564:dw

Best ResponseYou've already chosen the best response.2Now we distribute the 3 on the left side. To distribute a number by a quantity in parentheses, we multiply the number outside the parentheses by each term inside the parentheses. Let's do just the left side first.

Best ResponseYou've already chosen the best response.2Yes, we are using the distributive property of multiplication over addition on the left side. You see, 3(x + 1) turns into 3 * x + 3 * 1. We will simplify that in the next step.

Best ResponseYou've already chosen the best response.2Now let's do the distributive property on the right side. dw:1433462795731:dw

Best ResponseYou've already chosen the best response.2You need to be careful with the signs on the left side.

Best ResponseYou've already chosen the best response.2Now we collect like terms on the right side. 2 and 4 are like terms. They both have no variable. We can combine them together. dw:1433462994203:dw

Best ResponseYou've already chosen the best response.2Since we are solving for x, we want x by itself on the left side and the numbers by themselves on the right side. Let's deal with the terms with x first. We see 2x on the right side. Since the term 2x and the term 2 (both on the right side) are being added together, we add 2x to both sides to move the 2x to the left side. dw:1433463153571:dw

Best ResponseYou've already chosen the best response.0then you add 3 to both sides? Or do you get rid of x?

mathstudent55

Best ResponseYou've already chosen the best response.2Subtract is correct. Now we have all terms with x on the left side. Now we need to get all terms that are just numbers on the right side. We see on the left side that 3 is being added to 5x. We want that 3 on the right side, so we subtract 3 from both sides.

Best ResponseYou've already chosen the best response.0divide both sides by positive 5

mathstudent55

Best ResponseYou've already chosen the best response.2We still want the x by itself, but there is a 5 with the x. The 5 is multiplying the x. We do the opposite operation to multiplication which is division. We divide both sides by 5.

Best ResponseYou've already chosen the best response.2One final thing. With many problems, you answer them, and you don;t really know whether the answer is correct or incorrect until your teacher grades your work. With an equation, we can find out by ourselves if x = 1 is really correct or not.

Best ResponseYou've already chosen the best response.0you fill in the number?

Best ResponseYou've already chosen the best response.2By stating that x = 1, we are saying that if we plug in 1 for x in the equation, the equation will be true. Let's check it for ourselves: In the second line below, I replaced x with our solution, 1. dw:1433463548144:dw

Best ResponseYou've already chosen the best response.2Now we work out the math to see if the statement above is true. If it is true, then x = 1 is the correct solution.
