Find the decimal equivalent of 2 1/3
2 1/3 = 7/3 = 2.333333

(4x + 9)/ 2.333333 = 3x / 0.5 Now cross multiply
0.5 * (4x + 9) = 3x * 2.333333
2x + 4.5 = 7x Transfer 2x to the right side.
4.5 = 5x
x = 4.5/5
x = 0.9

We'd best check this one
Left hand side.
(4x + 9)/2.333333
(4*0.9 + 9)/2.333333
(3.6 + 9)/2.333333
12.6/2.333333
5.4

Right hand side
3x/0.5
= 3*0.9/0.5
= 2.7/0.5
= 5.4

And it checks.
