Can you help me solve for x on this equation 2x+8=3x-4

Answer:
12
Step-by-step equation:
2x + 8 = 3x - 4
2x = 3x - 4 - 8
2x = 3x - 12
2x - 3x = -12
-1x = -12
x = -12 / -1
x = 12
Proof:
2(12) + 8 = 3(12) - 4
24 + 8 = 3(12) - 4
24 + 8 = 36 - 4
32 = 36 - 5
32 = 32 → both sides of the equation are equal, our answer is correct

Answer: 12
Step-by-step explanation:
2x + 8 = 3x - 4
In order to solve for x, we must isolate x. We can do this by moving all of the numbers with "x" in it to the left side of the equal side, and move everything else to the right of it!
Let's start off by subtracting 8 from both sides. Remember : what you do to one side, you must do it to the other.
2x + 8 - 8 = 3x - 4 - 8
Simplify!
2x = 3x - 12
Now, let's subtract 3x from both sides.
2x - 3x = 3x - 12 - 3x
Simplify!
-x = -12
Divide both sides by -1.
-x ÷ -1 = -12 ÷ -1
Simplify.
x = 12

Answer: the slope would be -4/3 and the y intercept is 2
Step-by-step explanation: you would have to divide both sides by 3 to get y by itself. that leaves you with -4/3x + 2
1/2, 4/8, etc. Because they all equal to one half. <span />
