Question

Plsss help me!!

find x and y

y= x-5
y= -7x+11

Answer 1

x = 2

y = -3

Explanation:

make them equal to each other

x-5 = -7x + 11

8x = 16

x = 2

put 2 back in the equation to get y

y = 2 - 5

y = -3

Answer 2

x = 2

y = -3

Explanation:

Solve using substitution.

Substitute x-5 for y:

x - 5 = -7x + 11

Add 7x to both sides

8x - 5 = 11

Add 5 to both sides

8x = 16

Divide both sides by 8

x=2

Plug 2 back in for x to solve for y:

y = x - 5 = 2 - 5 = -3

(x, y)=(2, -3)
