Question

Name the y value of the solution to the system of equations.
Use substitution:

x = 2y - 3

3x + y = 12

(I WILL FAN AND MEDAL)

Answer 1

Plug the first equation in for x like this

3(2y-3)+y=12

Then solve for x when you get the x valuenplug the x value in for x in the problem to get your y value

Answer 2

x = 3 & y = 3

Answer 3

put x value in second 3 (2y-3)+y=12
6y-9+y=12
7y=12+9
7y=21
y=21/7=3
x=2y-3
x=2*3-3=6-3=3
