2x+7y=5 y=x+2 what does x and y equal and how do i get the answer?

The value of x equals - 1. The value of y equals 1.

2x + 7y = 5

y = x + 2

Because we have a value of y, we can plug it into the first equation to solve for x.

2x + 7 (x + 2) = 5

Distributive property.

2x + 7x + 14 = 5

Simplify like terms.

9x + 14 = 5

Subtract 14 from both sides.

9x = - 9

Divide both sides by 9.

x = - 1

Now that we have a value for x, we can solve for y.

y = (-1) + 2

y = 1
