Question

Use Substitution to solve each system of equations.

Answer 1

x = -3

y = -2

(-3, -2)

Explanation:

x - 7y = 11

5x + 4y = -23

-----------------------

-5 (x - 7y = 11)

-5x + 35y = -55

--------------------------

-5x + 35y = -55

5x + 4y = -23

39y = -78

÷39 ÷39

y = -2

-----------------------------

x - 7y = 11

x -7(-2) = 11

x + 14 = 11

-14 -14

x = -3

I hope this helps!
