Isolate x term: First, we want to isolate the term containing x on one side of the equation. To do this, we can start by subtracting 42 from both sides of the equation to get the term with x by itself.42−(x/2)=66−(x/2)=66−42
Subtract 42: Now, we perform the subtraction on the right side of the equation.−2x=24
Get rid of division: Next, we want to solve for x, which means we need to get rid of the division by 2. To do this, we multiply both sides of the equation by 2.2×(−(2x))=24×2
Multiply by −1: Multiplying both sides by 2 cancels out the division by 2 on the left side and we can simplify the right side.−x=48
Multiply by −1: Multiplying both sides by 2 cancels out the division by 2 on the left side and we can simplify the right side.−x=48 We have −x=48, but we want to find the value of x, not −x. To find x, we multiply both sides of the equation by −1.−x×−1=48×−1
Multiply by −1: Multiplying both sides by 2 cancels out the division by 2 on the left side and we can simplify the right side.−x=48We have −x=48, but we want to find the value of x, not −x. To find x, we multiply both sides of the equation by −1.−x×−1=48×−1Multiplying by −1 gives us the value of x.21
