Question

If 2x - 6 = -2, What is the value of x-4?

Answer 1

Solution in the attachment; hope it helped.

Answer 2

To find the value of x - 4, we first need to find the value of x.

So, we must solve 2x - 6 = - 2

To do this, we must isolate x.

So, let's start off by adding 6 to both sides, i.e., L.H.S. and R.H.S.

2x - 6 + 6 = -2 + 6

Simplify.

2x = 4

Divide both sides by 2.

$\dfrac{2x}{2} = \dfrac{4}{2}$

x = 2

So, now let's plug in "2" for x in x - 4.

x - 4

⇒ (2) - 4

Simplify.

-2 

So, the value of "x - 4" is -2.
