Solve for x:
−7(x+4)−2=5(2−x)
To solve the equation −7(x+4)−2=5(2−x), follow these steps:
- Step 1: Distribute the coefficients across the terms inside the parentheses.
On the left side: Apply −7 to (x+4):
−7⋅x+(−7)⋅4=−7x−28.
On the right side: Apply 5 to (2−x):
5⋅2+5⋅(−x)=10−5x.
- Step 2: Substitute the distributed expressions back into the equation:
−7x−28−2=10−5x.
- Step 3: Simplify both sides by combining like terms:
The left side simplifies to: −7x−30.
Thus, the equation becomes: −7x−30=10−5x.
- Step 4: Get all terms involving x on one side of the equation:
Add 5x to both sides: −7x+5x−30=10.
This simplifies to: −2x−30=10.
- Step 5: Isolate the term with x on one side:
Add 30 to both sides: −2x=40.
- Step 6: Solve for x by dividing by −2:
x=−240=−20.
Therefore, the solution to the equation is x=−20.
