Answer:

x = 16.5

Step-by-step explanation:

Firstly, open the brackets

6÷15x- 45 = 2÷3x+18

Rewrite the equation as:

6/15x-45 = 2/3x+18

cross multiply

6×3x+18 = 2×15x-45

18x+108 = 30x-90

collect like terms

18x-30x = -90-108

-12x = -198

divide both sides by -12

-12x/-12 = -198/-12

x = 33/2

x = 16.5
