5\times \frac{72}{4}=2\times 3x
Multiply both sides of the equation by 10, the least common multiple of 2,5.
5\times 18=2\times 3x
Divide 72 by 4 to get 18.
90=2\times 3x
Multiply 5 and 18 to get 90.
90=6x
Multiply 2 and 3 to get 6.
6x=90
Swap sides so that all variable terms are on the left hand side.
x=\frac{90}{6}
Divide both sides by 6.
x=15
Divide 90 by 6 to get 15.
