Solve 4.2x-3/2=124

$$4.2 x - \frac { 3 } { 2 } = 124$$

Solve for x

$$x = \frac{1255}{42} = 29\frac{37}{42} \approx 29.880952381$$

Steps for Solving Linear Equation

Add \frac{3}{2} to both sides.

$$4.2x=124+\frac{3}{2}$$

Convert 124 to fraction \frac{248}{2}.

$$4.2x=\frac{248}{2}+\frac{3}{2}$$

Since \frac{248}{2} and \frac{3}{2} have the same denominator, add them by adding their numerators.

$$4.2x=\frac{248+3}{2}$$

Add 248 and 3 to get 251.

$$4.2x=\frac{251}{2}$$

Divide both sides by 4.2.

$$x=\frac{\frac{251}{2}}{4.2}$$

Express \frac{\frac{251}{2}}{4.2} as a single fraction.

$$x=\frac{251}{2\times 4.2}$$

Multiply 2 and 4.2 to get 8.4.

$$x=\frac{251}{8.4}$$

Expand \frac{251}{8.4} by multiplying both numerator and the denominator by 10.

$$x=\frac{2510}{84}$$

Reduce the fraction \frac{2510}{84} to lowest terms by extracting and canceling out 2.

$$x=\frac{1255}{42}$$
