Answer 1

We're supposed to put the correct answer in each box? Thanks for clarifying.

What a contrived question. We plot.

Rejecting the negative solution we see intersection at x=7.

$S=2^7 + 12 = 128+12 = 140$

$S = 15(7)+35 = 20(7)=140 \quad\checkmark$

First Answer Box: 7

Second Answer Box: 140
