2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
23 + 5u = 17Subtract 17 23 from both sides:5u = -6Divide both sides by 5:u = -6/5
16 + 23 + 14 = 53
24 + 23 + 22 + 21 + 20 + 19 + 18 + 17 + 16 + 15 + 14 + 13 + 12 + 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 300
Are you for real?! Just substitute it. 17 plus 23 is 40.

-17/23 and the intercept is 25/23
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
23 + 5u = 17Subtract 17 23 from both sides:5u = -6Divide both sides by 5:u = -6/5
23 + 16 + 16 = 55
