Write Equation: Write down the given equation.We have the equation −(89)=v−(21).
Add to Isolate v: Add (1/2) to both sides of the equation to isolate v on one side.−89+21=v−21+21
Simplify Equation: Simplify both sides of the equation.To add fractions, we need a common denominator. The common denominator for 8 and 2 is 8.−(89)+(84)=v
Combine Fractions: Combine the fractions on the left side of the equation.−89+84=−85So, v=−85.
Check Solution: Check the solution by substituting v back into the original equation.−89=−85−21 We need a common denominator to combine the fractions on the right side.−85−84=−89 The left side equals the right side, so the solution is correct.
