Answer:
135 + 100h = 535
Step-by-step explanation:
to solve it would be 535-135= 400
then 400/100=4
135h + 100 = 535 no
135 - 100h = 535 no
135 + 100h =535 yes
135 + 100 = 535 no
For the one that is correct it would go like this
So h is the amount of hours which we do know but want to check
135 + 100h = 535
-135 -135
100h = 400
/100 /100
h = 4
And h is hours which we also got 4
so it would be 135 + 100h = 535
