4x+4y=12 , 2x+y=4 solve using elimination method

y=2 x=1

Step-by-step explanation:

Using the elimination method we can subtract the equations. the goal is to where the answer only has one variable. we can do this by subtracting two times the second equation from the first equation.

(4x+4y=12) - 2(2x+y=4)

= (4x+4y=12)-(4x+2y=8)

=2y=4

=y=2

now plug the y value into one of the original equations to solve for x

2x+2=4

2x=2

x=1

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
