Steps for Solving Linear Equation

Multiply both sides of the equation by 2.

$$\frac{1}{2}x\times 10.5=378$$

Convert decimal number 10.5 to fraction \frac{105}{10}. Reduce the fraction \frac{105}{10} to lowest terms by extracting and canceling out 5.

$$\frac{1}{2}x\times \frac{21}{2}=378$$

Multiply \frac{1}{2} times \frac{21}{2} by multiplying numerator times numerator and denominator times denominator.

$$\frac{1\times 21}{2\times 2}x=378$$

Do the multiplications in the fraction \frac{1\times 21}{2\times 2}.

$$\frac{21}{4}x=378$$

Multiply both sides by \frac{4}{21}, the reciprocal of \frac{21}{4}.

$$x=378\times \frac{4}{21}$$

Express 378\times \frac{4}{21} as a single fraction.

$$x=\frac{378\times 4}{21}$$

Multiply 378 and 4 to get 1512.

$$x=\frac{1512}{21}$$

Divide 1512 by 21 to get 72.

$$x=72$$
