Best ResponseYou've already chosen the best response.3Using x, how do you express 5 times x? It's 5 * x or even simpler, 5x. Ok?

Best ResponseYou've already chosen the best response.3No. We are making an equation so we can find the answer. This is just one step in making and equation. A number multiplied by 5 is 5x. Now we add 5 to the product. We add 5 to 5x, so we get 5x + 5

Best ResponseYou've already chosen the best response.3Then we are told that after doing the operations, the answer is 10. That means 5x + 5 = 10 This is the equation we must solve for x.

Best ResponseYou've already chosen the best response.35x + 5 = 10 We want to isolate x. Since 5 is being added to 5x, we first subtract 5 from both sides. 5x + 5 = 10 5 5  5x = 5 Now x is being multiplied by 5. We want x alone, so we divide both sides by 5: 5x/5 = 5/5 x = 1 The answer is: the number is 1

Best ResponseYou've already chosen the best response.3Now we can check to see if the answer is correct. We go back to the original problem: "A number is multiplied by 5. If 5 is added to the product, you get 10. what is the number?" We calculated the number to be 1, so let;'s see if it really works. "A number is multiplied by 5. 5 * 1 = 5 If 5 is added to the product, you get 10. 5 + 5 = 10 Yes, starting with 1, we do get 10, so 1 is the correct answer.
