simplify (-7/2 z+4)+(1/5 z-15)

simplify

(- \frac{7}{2} z + 4) + (\frac{1}{5} z - 15)

- \frac{33}{10} z - 11

Solution steps

(- \frac{7}{2} z + 4) + (\frac{1}{5} z - 15)

Simplify

(- \frac{7}{2} z + 4) + (\frac{1}{5} z - 15) : - \frac{7}{2} z + 4 + \frac{1}{5} z - 15

= - \frac{7}{2} z + 4 + \frac{1}{5} z - 15

Group like terms

= - \frac{7}{2} z + \frac{1}{5} z + 4 - 15

Factor out common term

z

= z (- \frac{7}{2} + \frac{1}{5}) + 4 - 15

Subtract the numbers:

4 - 15 = - 11

= z (- \frac{7}{2} + \frac{1}{5}) - 11

Simplify

z (- \frac{7}{2} + \frac{1}{5}) : - z \frac{33}{10}

= - z \frac{33}{10} - 11

= - \frac{33}{10} z - 11

(x + 2)^{2} - 3

\frac{7 x}{x + 1} + \frac{7}{x ^{2} - 1}

\frac{- 3 ^{- 2}}{4 ^{- 1}}

(- 4 x - 3) (2 x^{2} - 3 x + 4)

\frac{4 2 ^{642}}{22}
