3\left(5.4+x\right)=7.2\times 6
Multiply both sides by 6.
16.2+3x=7.2\times 6
Use the distributive property to multiply 3 by 5.4+x.
16.2+3x=43.2
Multiply 7.2 and 6 to get 43.2.
3x=43.2-16.2
Subtract 16.2 from both sides.
3x=27
Subtract 16.2 from 43.2 to get 27.
x=\frac{27}{3}
Divide both sides by 3.
x=9
Divide 27 by 3 to get 9.
