Question

Need help with system:
-4x-2y=14
-10x+7y=-25

Answer 1

what are you trying to do? substitute?

Answer 2

nevermind

Answer 3

-4x-2y=14

Since -4x does not contain the variable to solve for, move it to the right-hand side of the equation by adding 4x to both sides.
-2y=4x+14

Divide each term in the equation by -2.
-(2y)/(-2)=(4x)/(-2)+(14)/(-2)

Simplify the left-hand side of the equation by canceling the common factors.
y=(4x)/(-2)+(14)/(-2)

Simplify the right-hand side of the equation by simplifying each term.
y=-2x-7

Answer 4

-10x+7y=-25

Since -10x does not contain the variable to solve for, move it to the right-hand side of the equation by adding 10x to both sides.
7y=10x-25

Divide each term in the equation by 7.
(7y)/(7)=(10x)/(7)-(25)/(7)

Simplify the left-hand side of the equation by canceling the common factors.
y=(10x)/(7)-(25)/(7)

Simplify the right-hand side of the equation by simplifying each term.
y=(5(2x-5))/(7)
