Solve for X:
−8(2−x)=21+x
To solve the equation −8(2−x)=21+x, we will follow these detailed steps:
- Step 1: Distribute the −8 to both terms inside the parentheses:
−8(2−x)=−8×2+(−8)×(−x)=−16+8x.
- Step 2: Rewrite the equation from our distribution:
−16+8x=21+x.
- Step 3: Move all x-terms to one side and constants to the other. Subtract x from both sides:
8x−x=21+16.
- Step 4: Simplify both sides:
7x=21+16.
- Step 5: Combine like terms on the right side:
Convert 16 to an equivalent fraction of 232 so we can sum with 21:
7x=21+232=233.
- Step 6: Solve for x by dividing by 7:
x=233×71=1433.
Therefore, the solution to the equation is x=1433.
The choice : 1433
matches our solution.
