Question

how to solve 15(x-9)-2(x-12)+5(x+6)=0

Answer 1

15x-135-2x+24+5x+30=0
15x-2x+5x=135-24-30+0
18x=81
x=81/18
x=9/2

Answer 2

15(x-9)-2(x-12)+5(x+6)=0
simplifying the equation
15x-135-2x-24+5x+6=0
18x-153=0
18x=0+153
x=153÷18
x=8.5
if to simplify more you will have to put the value of x in the equation
i don't know that it is right or wrong
