Answer:
x = 2
Step-by-step explanation:
<em>Distribute</em>
3 (−4) = 2 (−2+1)
3 − 12 = 2 (-2x +1)
<em>Distrubute again</em>
3x - 12 = -4x + 2
<em>Add twelve to both sides of the equation</em>
<em>Simpfly</em>
3x = -4x + 14
<em>Add 4x to both sides of the equation</em>
<em>simpfly</em>
7x = 14
<em>Divide both sides of the equation by the same term</em>
<em>Simpfly</em>
x = 2

Answer:
x = -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2/3x + -1/2 = 2x + 5/6
Step 2: Subtract 2x from both sides.
2/3x + -1/2 - 2x = 2x + 5/6 - 2x
Step 3: Add 1/2 to both sides.
-4/3x + -1/2 = 5/6
-4/3x + -1/2 + 1/2 = 5/6 + 1/2
-4/3x = 4/3
Step 4: Multiply both sides by 3/(-4).
(-3/4) * (-4/3x) = (3/-4) * (4/3)
x = -1
