Question

Simplify the following expressions:

10x + 6 + 2(x + 5)
6 - 5(x + 2)
-2x - 10(2 + 4x)
6 - (x + 3)
3x - (x + 10) + 12

Answer 1

10x + 6 + 2(x + 5) =

= 10x + 6 + 2x + 10 = 12x + 16

6 - 5(x + 2) = 6 - 5x - 10 = -5x - 4

-2x - 10(2 + 4x) =

= -2x - 20 - 40x = -42x - 20

6 - (x + 3) = 6 - x - 3 = -x + 3

3x - (x + 10) + 12 =

= 3x - x - 10 + 12 = 2x + 2
