Solve u+3/5=-1/4

$$u + \frac { 3 } { 5 } = - \frac { 1 } { 4 }$$

Solve for u

$$u=-\frac{17}{20}=-0.85$$

Steps for Solving Linear Equation

Subtract \frac{3}{5} from both sides.

$$u=-\frac{1}{4}-\frac{3}{5}$$

Least common multiple of 4 and 5 is 20. Convert -\frac{1}{4} and \frac{3}{5} to fractions with denominator 20.

$$u=-\frac{5}{20}-\frac{12}{20}$$

Since -\frac{5}{20} and \frac{12}{20} have the same denominator, subtract them by subtracting their numerators.

$$u=\frac{-5-12}{20}$$

Subtract 12 from -5 to get -17.

$$u=-\frac{17}{20}$$
