9^(x+2)=2(4x-5)
We move all terms to the left:
9^(x+2)-(2(4x-5))=0
We calculate terms in parentheses: -(2(4x-5)), so:We get rid of parentheses
2(4x-5)
We multiply parentheses
8x-10
Back to the equation:
-(8x-10)
9^(x+2)-8x+10=0
We add all the numbers together, and all the variables
-8x+9^(x+2)+10=0
We move all terms containing x to the left, all other terms to the right
-8x+9^(x+2)=-10
