Y=x+4 3x-4y=12 solve for x an y

y= -24

x= -28

Step-by-step explanation:

Substitute y= x + 4 into 3x - 4y = 12

3x - 4( x + 4) = 12

Solve to get -28.

Then replace the -28 into the y equation.

y = x + 4 into y = -28 + 4

Solve to get - 24

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
