Math Problem Statement
Solve for x. Justify each step. Given: -2(2x+3) +1 = -x-13+3x
Solution
We are tasked with solving for in the equation:
Step 1: Distribute the on the left-hand side.
Distribute the across the terms inside the parentheses:
This simplifies to:
Step 2: Combine like terms on both sides.
On the left-hand side, combine :
On the right-hand side, combine the -terms :
Step 3: Move all terms involving to one side.
Add to both sides to eliminate the on the left-hand side:
This simplifies to:
Step 4: Isolate the -term.
Add 13 to both sides to move the constant term to the left-hand side:
This simplifies to:
Step 5: Solve for .
Divide both sides by 6 to isolate :
Thus, the solution is:
