Answer:

x = 7

Explanation:

Solve equation [2] for the variable y

[2] y = - 2

Plug this in for variable y in equation [1]

[1] (-2) - 2x = -16

[1] - 2x = -14

Solve equation [1] for the variable x

[1] 2x = 14

[1] x = 7

Solution:
y = -2
x = 7

Solve each system by substitution. 1) y= 2x - 16 y= -2-example-1
