Solve (72div3.6)*30x=(-108div3.6)*30x

$$(72 \div 3.6) \times 30x=(-108 \div 3.6) \times 30x$$

Solve for x

$$x=0$$

Steps for Solving Linear Equation

Cancel out 30 on both sides.

$$\frac{72}{3.6}x=\frac{-108}{3.6}x$$

Expand \frac{72}{3.6} by multiplying both numerator and the denominator by 10.

$$\frac{720}{36}x=\frac{-108}{3.6}x$$

Divide 720 by 36 to get 20.

$$20x=\frac{-108}{3.6}x$$

Expand \frac{-108}{3.6} by multiplying both numerator and the denominator by 10.

$$20x=\frac{-1080}{36}x$$

Divide -1080 by 36 to get -30.

$$20x=-30x$$

Add 30x to both sides.

$$20x+30x=0$$

Combine 20x and 30x to get 50x.

$$50x=0$$

Product of two numbers is equal to 0 if at least one of them is 0. Since 50 is not equal to 0, x must be equal to 0.

$$x=0$$
