Answer:
x = 3
Step-by-step explanation:
3(x + 2) = 6(x - 1) + 3
Divide both sides by 3.
x + 2 = 2(x - 1) + 1
Distribute the 2 on the right side.
x + 2 = 2x - 2 + 1
Combine like terms on the right side.
x + 2 = 2x - 1
Add 1 to both sides. Subtract x from both sides.
3 = x
x = 3

Answer:
the error is in step 2.
0.25x was added to -0.75x with an incorrect result of +0.50x.
Step-by-step explanation:
The incorrect step is ...
Step 2: negative 1.50 = 0.50 x
This is the result of an attempt to add 0.25x to both sides of the equation. The correct step would be ...
-1.50 -0.25x = -0.75x . . . . . . . result from Step 1
-1.50 -0.25x +0.25x = -0.75x +0.25x . . . . . add 0.25x to both sides
-1.50 = -0.50x . . . . . . . . . . . . . the correct result from the addition (Step 2)
__
The correct result is ...
x = -1.50/-0.50 = 3 . . . . . Step 3
