Solve 1.5*3+6*3=4.5*x

$$1.5 \times 3+6 \times 3=4.5 \times x$$

Solve for x

$$x=5$$

Steps for Solving Linear Equation

Multiply 1.5 and 3 to get 4.5.

$$4.5+6\times 3=4.5x$$

Multiply 6 and 3 to get 18.

$$4.5+18=4.5x$$

Add 4.5 and 18 to get 22.5.

$$22.5=4.5x$$

Swap sides so that all variable terms are on the left hand side.

$$4.5x=22.5$$

Divide both sides by 4.5.

$$x=\frac{22.5}{4.5}$$

Expand \frac{22.5}{4.5} by multiplying both numerator and the denominator by 10.

$$x=\frac{225}{45}$$

Divide 225 by 45 to get 5.

$$x=5$$
