4x-2=90 wha is the answer to this problem?
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 :)
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
92รท4=23
\(x=23\)
