Question

I NEED HELP!!!!!
7x-9=4x+90

Answer 1

Your answer would be 33

Answer 2

33

Explanation:

Our whole goal is to get x "alone"

7x-9=4x+90

Start by subtracting 4x from each side (7x-4x)-9=(4x-4x)+90

3x-9=90

Now, add 9 to each side 3x-9+9=90+9

3x=99

Now divide 3 from each side (3x/3)=99/3

x=33
