Answer:

x = 6

Step-by-step explanation:

We want to SOLVE the equation 4x-4=2x+8, that is, find the value of x that makes the equation true.

Start by subtracting 2x from both sides (which isolates x on the left):

2x - 4 = 8

Isolate 2x by adding 4 to both sides:

2x = 12

Dividing both sides by 2, we get x = 6.

What is y=-4/3x +6. y=2

Mekhanik [1.2K]

The given equation is:
[/tex]y=-\frac{4}{3}x+6 [/tex] and we need to evaluate this for y=2.
So, first step is to plug in 2 for y in the above equation. Therefore,

$2=-\frac{4}{3} x+6$
$2*3=-\frac{4}{3} x*3+6*3$ Multiply each sides by common denominator 3
$6=-4x+18$
6-18= -4x Subtract 18 from each sides.
-12=-4x
$-\frac{12}{-4} =-\frac{4x}{-4}$
So, x=3
