Solve don't know what to do
3x/10=9/4

3x / 10 = 9 / 4      First, isolate the variable by multiplying each side by 10
3x = 90 / 4           Then, divide each side by 3
x = 30 / 4             Now simplify
x = 15/2

3x/10=9/4

Multiply both sides by 10 to isolate the variable
3x = 90/4 

Then, divide 90 by 4 which gives you 22.5

After that, divide 22.5 by 3, which gives you 7.5

The final answer is either 15/2 or 7.5
