Solve for x: \sf 3(2x - 5) = 6x - 15

Question

Solve for x:

`\sf 3(2x - 5) = 6x - 15`

Answer 1

3(2x-5)=6x-15 or,6x-15=6x-15 or,6x-6x=15-15 therefore x = 0

Explanation:

Answer 2

Explanation:

`\bold{3(2x - 5) = 6x - 15}`

`\longrightarrow \: 6x - 10 = 6x - 15`

`\longrightarrow \: 6x - 6x = - 15 + 10`

`\longrightarrow \: 0 = - 5`

`\longrightarrow \fcolorbox{red}{yellow}{x = 0}`

To prove that the x =0

putting the value of x

`3(2x - 5) = 6x - 15`

`\longrightarrow \: 3(2 * 0 - 5) = 6 * 0 - 15`

`\longrightarrow 0 - 15 = 0 - 15`

`\longrightarrow \: - 15 = - 15`

`\longrightarrow \fcolorbox{red}{green}{LHS = RHS}`

hence its proved
