Question

Solve the equations using systematical method. a)3-2(2-y)=7​

Answer 1

3-2(2-y)=7

3-4+2y=7

1+2y=7

2y=7-1

2y=6

y=6/2

y=3

Answer 2

✰✰|| Given ||✰✰

• 3 - 2 ( 2 - y ) = 7

✰✰|| To Find ||✰✰

• 3 - 2 ( 2 - y ) = 7 solve it with systematical method

✪|| Solution ||✪

3 - 2 ( 2 - y ) = 7

↬ 1 ( 2 - y ) = 7

↬ 2 - y = 7

↬ - y = 7 - 2

↬ - y = 5

↬ y = 5 × ( - )

↬ y = - 5

Value of y = - 5
