Solve 3d+d-7=25/4

$$3 d + d - 7 = \frac { 25 } { 4 }$$

Solve for d

$$d = \frac{53}{16} = 3\frac{5}{16} = 3.3125$$

Steps for Solving Linear Equation

Combine 3d and d to get 4d.

$$4d-7=\frac{25}{4}$$

Add 7 to both sides.

$$4d=\frac{25}{4}+7$$

Convert 7 to fraction \frac{28}{4}.

$$4d=\frac{25}{4}+\frac{28}{4}$$

Since \frac{25}{4} and \frac{28}{4} have the same denominator, add them by adding their numerators.

$$4d=\frac{25+28}{4}$$

Add 25 and 28 to get 53.

$$4d=\frac{53}{4}$$

Divide both sides by 4.

$$d=\frac{\frac{53}{4}}{4}$$

Express \frac{\frac{53}{4}}{4} as a single fraction.

$$d=\frac{53}{4\times 4}$$

Multiply 4 and 4 to get 16.

$$d=\frac{53}{16}$$
