5 (3x - 20) = 10
After you factor in 5, this can be rewritten as 5(3x) - 5(20) = 10
Multiply 5 to 3x and 5 to 20, it becomes 15x - 100 = 10
Since the x has to be only on one side, to get rid of -100 on the left side, add 100 to both sides.
15x - 100 + 100 = 10 + 100 ----> 15x = 110
And then, divide the both side by 15, which becomes x = 110/15
Simplify the fraction to get x = 22/3
Or in decimal form x = 7.33333...(repeating)
