9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.

(5, 1)
No. It equals 15.
15
Negative 15 plus positive 20 equals 20 minus 15, which equals 5.
x=5
5 + 5 + 5 = 15
no it equls 15
x = 15
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
it can't equal 550....i think it equals 15
It doesn't, it equals 15.
-15 plus 20 is 5.
That equals 28
