Isolate variable w: First, we need to isolate the variable w on one side of the equation. To do this, we will subtract 18 from both sides of the equation to eliminate the constant term on the left side.2w+18−18=12−18
Simplify both sides: Now, we simplify both sides of the equation by performing the subtraction.2w=12−182w=−6
Solve for w: Next, we need to solve for w by dividing both sides of the equation by the coefficient of w, which is 2.22w=2−6
Perform division: Finally, we perform the division to find the value of w.w=2−6w=−3
