Identify Goal: Identify the goal of the problem. We need to solve for w in the equation 15−6w=22.
Isolate Term: Isolate the term containing w on one side of the equation. To do this, we can subtract 15 from both sides of the equation to get −(6w)=22−15.
Perform Subtraction: Perform the subtraction on the right side of the equation. 22−15 equals 7, so the equation now reads −(w/6)=7.
Get Rid of Negative Sign: To solve for w, we need to get rid of the negative sign and the division by 6. We can multiply both sides of the equation by −6 to do this. −6×−(6w)=7×−6.
Perform Multiplication: Perform the multiplication on both sides of the equation. The left side simplifies to w because −6×−(61) equals 1, and the right side becomes −42 because 7×−6 equals −42. So, w=−42.
