Question

3 + 2(2x + 8) = 1 is equivalent to:

Answer 1

Answer: -9/2

Explanation:

3 + 2(2x + 8) = 1

3 + 4x + 16 = 1

19 + 4x = 1

4x = -18

x = -18/4 = -9/2

Answer 2

x =
`-(9)/(2)`

Explanation:

=> 3+2(2x+8) = 1

=> 3+4x+16 = 1

=> 4x+19 = 1

=> 4x = 1-19

=> 4x = -18

Dividing both sides by 4

=> x =
`-(18)/(4)`

=> x =
`-(9)/(2)`
