Question

1-(7 – 4x) = 9 Solve for x​

Answer 1

15/4

Explanation:

Answer 2

`1 - (7 - 4x) = 9 \\ 1 - 7 + 4x = 9 \\ - 6 + 4x = 9`

and 6 to either sides:

`( - 6 + 4x) + 6 = 9 + 6 \\ 4x = 15`

divide all sides by 4:

`(4x)/(4) = (15)/(4) \\ \\ { \underline{ \underline{x \: \: is \: \: (15)/(4) }}}`
