To get from −8 − 8 to the answer you really want, just take the absolute value! That is, to find the distance between<span> any </span>two<span> real numbers: subtract them in any order</span>
I think it's 26.70 if I remember what a decimal is.
5x + 20 = 70
5x = 70 - 20
5x = 50
x = 50/5
x = 10
5(10) + 20 = 70
50 + 20 = 70
70 = 70
hope this helps :)
