Answer :
5(2x-3)=155
10x-15=155(solve/multiply 5 by the numbers/variables in the parentheses first)
10x=170(add 15 to each side)
Divide 170 by 10x
170÷10x=17
x=17
10x-15=155(solve/multiply 5 by the numbers/variables in the parentheses first)
10x=170(add 15 to each side)
Divide 170 by 10x
170÷10x=17
x=17
