Question

What's the answer? Anybody know?

2x + 3x + 5 + 9
-3x + 6x – 4 + 2
10x + 2 – 4x + 10
11x – 9x + 3x – 12 + 3
15 + 2x + 3x - 10

Answer 1

1.) 5x + 14 : (2x + 3x = 5x) (5 + 9=14)

2.) 3x - 4 : (-3x + 6x = 3x) (-4 + 2 = -4)

3.) 6x + 12 : (10x - 4x = 6x) (2 + 10 = 12)

4.) 5x - 9 : ((11x - 9x = 2x) + 3x = 5x) (-12 + 3 = -9)

5.) 5 + 5x (15 - 10 = 5) (2x + 3x = 5x)
