Steps by steps
5(x+5)<85
Divide each term by 5 and simplify.
5(x+5)÷5<85÷5
Reduce the expression by cancelling the common factors.
x+5<85÷5
Divide 85 by 5.
x+5<17
Move all terms NOT containing "x" to the right side of the inequality.
Subtract 5 from both sides of the inequality.
x<-5+17
Add -5 and 17.
=x<12
