Question

42 -(2x +32) +12 :2 =6

134 - 2 . {156 - 6.[54 -2.(9+6) ] } x=86

 

Answer 1

42 -(2x + 32) + 12 :2 =6

42 - 2x - 32 + 6 = 6

42 - 2x - 32 = 0

42 - 2x = 32

2x = 42 - 32 = 10

x = 5

134 - 2 . {156 - 6.[54 -2.(9+6) ] } x = 86

134 - 2.{ 156 - 6.[54 - 2 . 15 ]} x = 86

134 - 2.{ 156 - 6 . 24} x = 86

134 - 2. 12 .x = 86

134 - 24x = 86

24x = 48

x = 2 

Answer 2

\(42-\left(2x+32\right)+12:2=6\)

\(\Rightarrow42-2x-32=0\)

\(\Rightarrow2x=10\)

\(\Rightarrow x=5\)
