5 + n = 23 n = 18 18 - 5 = 13 ■
23 + 5u = 17Subtract 17 23 from both sides:5u = -6Divide both sides by 5:u = -6/5
8 plus 15 = 23
74 + 23 = 97
It is: 157+23 = 180
-23
It is an algebraic expression which equals a + 28.

1 1/2 plus 4 2/3 equals 5 3/5.
(4, 5)
3p+5+p = -23 3p+p = -23-5 4p = -28 p = -7
5 + n = 23 n = 18 18 - 5 = 13 ■
x = 2
3x + 5 = 6x + 23 -3x = 18 x = -6
42
you just add eight and the answer is 5
23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2
