Question

What's the value f x?
$5x-6=3x-8$

Answer 1

Answer:

• -1

Step-by-step explanation:

Given equation,

⇒ 5x - 6 = 3x - 8

Subtracting 3x from both sides :

⇒ 5x – 6 – 3x = 3x – 8 – 3x

⇒ 2x – 6 = – 8

Adding 6 to both sides we get :

⇒ 2x – 6 + 6 = – 8 + 6

⇒ 2x = – 2

Dividing both sides by 2 we get :

⇒ 2x/2 = – 2/2

⇒ x = – 1

Therefore,

• The value of x is -1

Answer 2

Answer:

$\sf \boxed{\bold{x=-1}}$

Solving Stepwise:

$\dashrightarrow \sf 5x-6=3x-8$

add 6 on both sides

$\dashrightarrow \sf 5x-6+6=3x-8+6$

simplify

$\dashrightarrow \sf 5x=3x-2$

subtract both sides by 3x

$\dashrightarrow \sf 5x-3x=3x-2-3x$

simplify

$\dashrightarrow \sf 2x=-2$

divide both sides by 2

$\dashrightarrow \sf \dfrac{2x}{2} =\dfrac{-2}{2}$

simplify

$\dashrightarrow \sf x =-1$

Check for the answer:

insert x = -1

$\hookrightarrow \sf 5(-1)-6=3(-1)-8$

$\hookrightarrow \sf -5-6=-3-8$

$\hookrightarrow \sf -11=-11$

L.H.S = R.H.S. Hence the statement x = -1 is correct.
