-3(2x -2) +5x = -4x + 2(x-1)
-6 + 6 + 5x = -4x - 2x - 2
Your first term on the left side should include x. Your second term on the right side should be positive. This gives you:
Grouping like terms, we may write:
Combining the like terms, we find:
Can you proceed from here?
No. If you are unsure about your solution, substitute it into the original equation to see if it satisfies the equation. For , we get:
This is not true, so the solution is wrong.
We may first add to both sides:
Combining like terms, we find:
Now subtract 6 from both sides, and you get:
Now, checking the solution:
This is true so we know the solution is correct.
