What is the value of x in the solution to this system of equations? 4x+7y=85

x=2y−5

A. x = -9
B. x = 9
C. x = 8
D. x = 3

B

Step-by-step explanation:

I used substitution to solve this system. I'll run through all of my steps below:

I'm going to replace the 'x' values in the first equation with the entire second equation.

Now that we know what y equals, we can go back and solve for x.

Hope this helps!

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
