Best ResponseYou've already chosen the best response.0do you move the x to the other side first or do you just solve

Best ResponseYou've already chosen the best response.0so the equation would look like this 2y=x6

Best ResponseYou've already chosen the best response.1Lol tyler. I'm asking you to pick a variable that we can solve for in order to substitute.

Best ResponseYou've already chosen the best response.1x − 2y = 6 Solve that equation for x now. :)

Best ResponseYou've already chosen the best response.0so you would substitute 0 for x and the equation (0)2y=6

Best ResponseYou've already chosen the best response.1where have you go that my friend

Best ResponseYou've already chosen the best response.1.uhm. We need to isolate x x − 2y = 6 Add 2y to both sides in order to make x be on its own. Whats x= now?

Best ResponseYou've already chosen the best response.1Okay now let's look at the second equation.

Best ResponseYou've already chosen the best response.1We know that x=2y+6 Now plug that value for x into this equation 2x − 4y = 10

Best ResponseYou've already chosen the best response.12(2y+6)4y=10 4y+124y=10 4y4y=0 12=10 Dang we did something wrong.

Best ResponseYou've already chosen the best response.0yeah maybe we entered the wrong equation

Best ResponseYou've already chosen the best response.1uhm lets try solving for x in the bottom equation? 2x4y=10

Best ResponseYou've already chosen the best response.1actually don't...it won't work again.

Best ResponseYou've already chosen the best response.1Are you okay if we try elimination?

karatechopper

Best ResponseYou've already chosen the best response.1Yay. x − 2y = 6 2x − 4y = 10 Okay so let's try to eliminate x, we will multiply the top equation by 2, Could you do that for me please?

Best ResponseYou've already chosen the best response.0you multiply everthing by two or what

Best ResponseYou've already chosen the best response.1We just wanted to multiply x2y=6 You should have gotten (2)x(2)(2)y=6(2)

Best ResponseYou've already chosen the best response.1okay what is a negative times a negative

anonymous

Best ResponseYou've already chosen the best response.0so its a positive 4y

Best ResponseYou've already chosen the best response.1now rewrite the equation we have.

Best ResponseYou've already chosen the best response.1Alright turn up.

karatechopper

Best ResponseYou've already chosen the best response.1So lets rewrite the whole thing. 2x+4y=12 2x − 4y = 10 Now, solve it out. As you can see...both variables cancel out... Did you post the right question? Also, the answer because we cannot solve it is.... No solution.

Best ResponseYou've already chosen the best response.0A system of equations is shown below: 6x − 2y = 3 (equation 1) 5x + 3y = 4 (equation 2) A student wants to prove that if equation 2 is kept unchanged and equation 1 is replaced with the sum of equation 1 and a multiple of equation 2, the solution to the new system of equations is the same as the solution to the original system of equations. If equation 2 is multiplied by 1, which of the following steps should the student use for the proof?

Best ResponseYou've already chosen the best response.0can you add these 2 equations and tell me what you get: 6x − 2y = 3 5x + 3y = 4

TheSmartOne

Best ResponseYou've already chosen the best response.0so basically, what is 6x + 5x 2y + 3y = 3 + 4
