5 + n = 23 n = 18 18 - 5 = 13 ■
5-2=3n=3
n = 3
n + 5 = 18 n = 13
5
n + 2 = 5, solve for n.n = 5 - 2n = 3
*
That would be 18+n. 5+3+2 = 5+3+n 10 = 8 + n 10-8 = n 2 = n and if you substitute 2 for n then you see that 5+3+2 = 5+3+2
your expression is this... n+5=3+12 n+5=15 n=10
20 = 5 + n/3 15 = n/3 n = 45
The answer is 37, because you substitute n in 5 to 12 plus 5n, the answer is 37.Hope it is correct.
