Solve 3=-3/4+x

$$3=- \frac{ 3 }{ 4 } +x$$

Solve for x

$$x = \frac{15}{4} = 3\frac{3}{4} = 3.75$$

Steps for Solving Linear Equation

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

$$-\frac{3}{4}+x=3$$

Add \frac{3}{4} to both sides.

$$x=3+\frac{3}{4}$$

Convert 3 to fraction \frac{12}{4}.

$$x=\frac{12}{4}+\frac{3}{4}$$

Since \frac{12}{4} and \frac{3}{4} have the same denominator, add them by adding their numerators.

$$x=\frac{12+3}{4}$$

Add 12 and 3 to get 15.

$$x=\frac{15}{4}$$
