Question

151-2.(x-6)=2227:17

Answer 1

151 - 2(x-6) = 2227 :17 = 131

2(x-6) = 151 - 131=20

x - 6 = 20 : 2=10

x = 10+6 =16

Answer 2

151-2.(x-6)=2227:17

151-2.(x-6)=131

2.(x-6)=151 - 131

2.(x-6)=20

x-6=20:2

x-6=10

x=10+6

x=16

Answer 3

\(151-2.\left(x-6\right)=2227:17\)

\(=151-2\cdot\left(x-6\right)=131\)

\(\Rightarrow2\cdot\left(x-6\right)=151-131=20\)

\(\Rightarrow x-6=20:2=10\)

\(\Rightarrow x=10+6=16\)
