Rearrange equation: First, we want to get all the terms with y on one side of the equation and the constant terms on the other side.2−81y=11+87yAdd 81y to both sides to move the y terms to the right side.2=11+87y+81y
Combine like terms: Now, combine like terms on the right side.2=11+(87+81)y2=11+88y2=11+y
Isolate variable: Next, we want to isolate y. Subtract 11 from both sides of the equation.2−11=y−9=y
