1) subtract 2 from both sides:
y-2 = 9x +2 -2
y-2 = 9x
2) divide both sides by 9:
(y-2)/9 = 9x/9
(y-2)/9=x
so it would be (g-10)/f
42
It’s 42 since if you would convert this
Using first the customary ruler and then the metric ruler, measure the length of the side of the wooden block. Remember to estimate to one place value beyond the rulers’ gradations.
(7+x)+x=15
I did trial and error to get x=4.
