Answer 1

\(2^3.5-3^2.2\)

\(=8.5-9.2\)

\(=40-18\)

\(=22\)

Answer 2

=8.5-9.2

=40-18

=22

Answer 3

2³ .5 - 3² .2

= 8.5 - 9.2

= 40- 18 

= 22

Answer 4

Answer 6

3 ( x - 2 ) + 5 = 20

=>3(x-2)=20-5

=>3(x-2)=15

=>x-2=15:3

=>x-2=5

=>x=7

Answer 7

3( x - 2 ) + 5 = 20

=> 3(x - 2) = 20 - 5

=> x - 2 = 15 : 3

=> x - 2 = 5

=> x = 5 + 2

=> x = 7
