Answer 2

18m + 22m = 40m c + 14c = 15c 4x + x + 4x + 2x + 6x + 12x = 25x 12y - 7y - y + 13y = 17y 25t - 13t = 12t 3a - 3a + 8a = 8a

Now let's simplify the entire expression: 40m + 15c + 25x + 17y + 12t + 8a + 6x + 4 + 3x = 7

Combine like terms: 40m + 15c + 34x + 17y + 12t + 8a + 4 = 7

Subtract 4 from both sides: 40m + 15c + 34x + 17y + 12t + 8a = 3

So the simplified expression is: 40m + 15c + 34x + 17y + 12t + 8a = 3
