Answer:

y = -10

Step-by-step explanation:

Step 1: Substitute -5 for x in the equation -5x + 7y = 5x + 2y

-5x + 7y = 5x + 2y

-5(-5) + 7y = 5(-5) + 2y

Step 2: Solve for y

-5(-5) + 7y = 5(-5) + 2y

25 + 7y + 25 - 7y = -25 + 2y + 25 - 7y

50 / -5 = -5y / -5

-10 = y

Answer: y = -10

Answer:

Step-by-step explanation:

Apply Only the Outside and Inside Method of the Foil Method.

$7 \times - \frac{1}{2} = - 3.5x$

$\frac{1}{2} \times 7x = 3.5x$

Add them together

$- 3.5x + 3.5x = 0$

So our b value is 0.
