Question

when solving the system below algebraically using the substitution method, which of the following could be an equation you could. create to solve for x?A) x = 3y - 3B) -2x + 6(2x + 11) = 6C) -2x - 6 = - 2x - 11D) -2 (3y - 3) + y = 11

Answer 1

We have that the solutions of the system are

`x\text{ = -6 and y = -1}`

So we are going to check which of the answers give that answer, we are going to try with A fisrt

`x\text{ = }3(-1)\text{ }-3\text{ = -6}`

So with A, the solutions are the same, so we have that the answer is A.
