Question

4x-2=90 wha is the answer to this problem?

Answer 1

Firstly, you want to get 4x alone, so to do this, you add 2 to both sides, as you always do the opposite operation.
This then becomes
4x=92
To get x alone, you then divide both sides by 4.
92/4=23
Therefore, x= 23
Hope this helps :)

Answer 2

Your goal is to get "x" by itself on one side

$4x-2=90$

Add +2 to each side

$4x-2+2=90+2$

$4x=92$

Divide 92 by 4

92÷4=23

$x=23$
