Question

2. Given 4(-x + 4) = 12 Prove x = 1​

Answer 1

`\large\bf{\orange{ \implies}} \: \tt \: \: 4 \: ( - x \: + \: 4) \: = \: 12`

`\large\bf{\orange{ \implies}} \: \tt \: \: - 4x \: + \: 16 \: = \: 12`

`\large\bf{\orange{ \implies}} \: \tt \: \: - 4x \: = \: 12 \: - 16`

`\large\bf{\orange{ \implies}} \: \tt \: \: - 4x \: = \: - 4`

`\large\bf{\orange{ \implies}} \: \tt \: \:x \: = \: \frac{ \cancel{- 4} \: \: ^(1) }{ \cancel{- 4}}`

`\large\bf{\orange{ \implies}} \: \bf \: \:x \: = \: 1`

`\Large\underbrace{\textrm{{{\color{blue}{Hence , Proved}}}}}`

Answer 2

Solve the equation

`\\ \sf \longmapsto 4(-x+4)=12`

`\\ \sf \longmapsto -4x+16=12`

`\\ \sf \longmapsto -4x=12-16`

`\\ \sf \longmapsto -4x=-4`

`\\ \sf \longmapsto x=(-4)/(-4)`

`\\ \sf \longmapsto x=1`
