Question

22-2.(x-9)=4⁵:4³

Answer 1

22-2(x-9)= 4^2

22-2(x-9)= 16

2(x-9)= 22-16

2(x-9)= 6

x-9= 6:2

x-9= 3

x= 3+9

x= 12

Answer 2

22-2x-18=4^5-3

2x+4=4²

2x+4=16

2x=16-4

2x=12

x=6

Answer 3

\(22-2\left(x-9\right)=4^5:4^3\\ \Leftrightarrow22-2\left(x-9\right)=4^2\\ \Leftrightarrow22-2\left(x-9\right)=16\\ \Leftrightarrow2\left(x-9\right)=6\\ \Leftrightarrow x-9=3\\ \Leftrightarrow x=12\)

Answer 4

22-2.(x-9)=4²

22-2.(x-9)=16

2.(x-9)=22-16

2.(x-9)=6

x-9=6:2

x-9=3

x=3+9

x=12

Vậy x = 12

Answer 5

\(22-2.\left(x-9\right)=4^2\\ 22-2\left(x-9\right)=16\\ 2\left(x-9\right)=22-16\\ 2\left(x-9\right)=6\\ x-9=6\div2\\ x-9=3\\ x=12\)
