Question

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

Answer 1

Answer:

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

Step-by-step explanation:

Answer 2

Step-by-step 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

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

$\longrightarrow \: 3(2 \times 0 - 5) = 6 \times 0 - 15$

$\longrightarrow 0 - 15 = 0 - 15$

$\longrightarrow \: - 15 = - 15$

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

hence its proved
