Solve E=-1/2+-5/9

$$E = \frac { - 1 } { 2 } + \frac { - 5 } { 9 }$$

Solve for E

$$E = -\frac{19}{18} = -1\frac{1}{18} \approx -1.055555556$$

Steps for Solving Linear Equation

Fraction \frac{-1}{2} can be rewritten as -\frac{1}{2} by extracting the negative sign.

$$E=-\frac{1}{2}+\frac{-5}{9}$$

Fraction \frac{-5}{9} can be rewritten as -\frac{5}{9} by extracting the negative sign.

$$E=-\frac{1}{2}-\frac{5}{9}$$

Least common multiple of 2 and 9 is 18. Convert -\frac{1}{2} and \frac{5}{9} to fractions with denominator 18.

$$E=-\frac{9}{18}-\frac{10}{18}$$

Since -\frac{9}{18} and \frac{10}{18} have the same denominator, subtract them by subtracting their numerators.

$$E=\frac{-9-10}{18}$$

Subtract 10 from -9 to get -19.

$$E=-\frac{19}{18}$$

Assign E

$$E≔-\frac{19}{18}$$
