Answer:

x = 0.9

Explanation:

4x + 9 / 2 1/3 = 3x / 0.5

Note 2 1/3 is equivalent to 7/3

Therefore, the equation becomes

4x + 9 / (7/3) = 3x / 0.5

Cross multiply,

0.5(4x + 9) = 3x(7/3)

Open/Remove the brackets,

= 2x + 4.5 = 21x/3

Again, cross multiply,

3(2x + 4.5) = 21x

6x + 13.5 = 21x

Carrying 6x to the other side,

13.5 = 21x - 6x

13.5 = 15x

Divide both sides by 15,

x = 13.5/15

x = 0.9
