How do you solve (37+s) + s=375

S = 169

37+s+s=375

37+2s=375

Subtract 37 from both sides

2s=338

Divide by 2 on both sides

S=169

(37+s) + s=375

We move all terms to the left:

(37+s) + s - (375) = 0

We add all the numbers together, and all the variables

(s+37) + s-375=0

We add all the numbers together, and all the variables

s + (s+37) - 375=0

We get rid of parentheses

s+s+37-375=0

We add all the numbers together, and all the variables

2s-338=0

We move all terms containing s to the left, all other terms to the right

2s=338

s=338/2

s=169
