You do the reverse and divide the 2 values to find out the last one
72/9 = 8
Do you get it?
you combine like terms first.
for example: 2x=2+5
add up the two plus 5 so that will give you seven then you're going to divide 2 by 7 so that you isolate the x and you'll get your answer.
Yes because if you solve it it will become -11k
<span>twice the sum of a number and seven is 8
2(x+7)=8</span>
