Solve the following system of equations by substitution and select the correct answer below:

2x - 4y = 24

4x - 12y = 36

x = 18, y = 3

x = 18, y = - 3

x = - 18, y = 3

x = - 18, y = - 3

Jenna Jarvis · Answer 1

X = (24+4y) / 2

4 (24+4y) / 2-12y=36

48+8y-12y=36

4y=12

y=3

2x-4x3=24

2x=36

x=18
