Please help me with these questions! Thx! :)

Answer 1

Hey there,

148 = 2x + 6(x + 10)

148 = 2x + 6x + 60

148 = 8x + 60
-60 - 60

88 = 8x
/8 /8

11 = x


6x + 4(-x - 14) = -42

6x -4x - 56 = -42

2x - 56 = -42
+ 56 + 56

2x = 14
/2 /2

x = 7


-101 = 7x -4(-3x - 8)

-101 = 7x + 12x + 32

-101 = 19x + 32
- 32 - 32

-133 = 19x
/19 /19

-7 = x

Hope I helped :)
