Question

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

Answer 1

Answer:

x = 7

Step-by-step 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
