Question

Solve for x. 5(x-10)=30-15x

Answer 1

`\boxed{\boxed{\sf x=4}}`

Explanation:

`\star \:\:\sf 5(x-10)=30-15x \: \:\star`

Expand:

`\Longrightarrow \sf 5x-50=30-15x`

Add 50 to both sides:

`\Longrightarrow \sf 5x-50+50=30-15x+50`

`\Longrightarrow \sf 5x=-15x+80`

Add 15x to both sides:

`\Longrightarrow \sf 5x+15x=-15x+80+15x`

`\Longrightarrow \sf 20x=80`

Divide both sides by 20:

`\Longrightarrow \sf \cfrac{20x}{20}=\cfrac{80}{20}`

`\Longrightarrow \sf x=4`
