Answer 1

`\\ \tt\hookrightarrow (x+4)/(2x+1)=(8)/(12)=2/3`

`\\ \tt\hookrightarrow 3(x+4)=2(2x+1)`

`\\ \tt\hookrightarrow 3x+12=4x+2`

`\\ \tt\hookrightarrow x=12-2`

`\\ \tt\hookrightarrow x=10`

Answer 2

x = 10

Explanation:

`(x+4)/(8)=(2x+1)/(12)`

Cross multiply:

`\implies 12(x+4)=8(2x+1)`

Expand brackets:

`\implies 12x+48=16x+8`

Collect and combine terms:

`\implies 48-8=16x-12x\\\\\implies 40=4x`

Divide both sides by 4:

`\implies x=10`
