Solve for X:
−21(x+41)=81
To solve the equation −21(x+41)=81, we will first eliminate the fraction by multiplying both sides by the common denominator. The common denominator here is 8, so we proceed as follows:
- Step 1: Multiply both sides by 8 to eliminate the fractions:
8(−21(x+41))=8×81
- Step 2: Simplify the left side:
−4(x+41)=1
- Step 3: Distribute −4 into the terms inside the parentheses:
−4x−1=1
- Step 4: Add 1 to both sides to isolate the term with x:
−4x=2
- Step 5: Divide both sides by −4 to solve for x:
x=−42=−21
Therefore, the solution to the equation is x=−21.
