Multiply: -2x + 8 = -4
Subtract 8 from both sides: -2x = -12
Divide by -2: x= 6

Check:
-2(6-4)=-4
-2(2)= -4
-4 = -4

Answer:

x=6

Explanation:

−2(x−4)=−4

Step 1: Simplify both sides of the equation.

−2(x−4)=−4

(−2)(x)+(−2)(−4)=−4(Distribute)

−2x+8=−4

Step 2: Subtract 8 from both sides.

−2x+8−8=−4−8

−2x=−12

Step 3: Divide both sides by -2.

−2x / -2 = -12 / -2

x=6

3. Rewrite -2x + 3y = 6 in slope intercept form.

zaharov [31]

The equation in slope-intercept form is:

$y=\frac{2}{3}x+2$

Further explanation:

The standard slope-intercept form is:

$y=mx+b$

Given equation is:

$-2x+3y=6$

In order to bring the equation in slope-intercept form we have to isolate y on left hand side of equation

So,

Adding 2x on both sides

$-2x+3y+2x=6+2x\\3y=2x+6$

Dividing both sides by 3

$\frac{3y}{3}=\frac{2x+6}{3}\\y=\frac{2x+6}{3}$

Simplifying

$y=\frac{2x+6}{3}\\y = \frac{2x}{3}+\frac{6}{3}\\y=\frac{2}{3}x+2$

The equation in slope-intercept form is:

$y=\frac{2}{3}x+2$
