simplify (1/3 x+4/7 y)-(2/3 x-3/4 y)

simplify

(\frac{1}{3} x + \frac{4}{7} y) - (\frac{2}{3} x - \frac{3}{4} y)

\frac{- 28 x + 111 y}{84}

Solution steps

(\frac{1}{3} x + \frac{4}{7} y) - (\frac{2}{3} x - \frac{3}{4} y)

Apply rule:

(a) = a

(\frac{1}{3} x + \frac{4}{7} y) = \frac{1}{3} x + \frac{4}{7} y

= \frac{1}{3} x + \frac{4}{7} y - (\frac{2}{3} x - \frac{3}{4} y)

\frac{1}{3} x = \frac{x}{3}

\frac{4}{7} y = \frac{4 y}{7}

- (\frac{2}{3} x - \frac{3}{4} y) = - \frac{2}{3} x + \frac{3}{4} y

= \frac{x}{3} + \frac{4 y}{7} - \frac{2}{3} x + \frac{3}{4} y

Join

\frac{x}{3} + \frac{4 y}{7} - \frac{2}{3} x + \frac{3}{4} y : \frac{- 28 x + 111 y}{4 \cdot 21}

= \frac{- 28 x + 111 y}{4 \cdot 21}

Multiply the numbers:

4 \cdot 21 = 84

= \frac{- 28 x + 111 y}{84}

6 b^{2} + 11 b + 3

v^{2} - v - 2

\frac{8 !}{( 8 - 2 ) ! ( 2 ! )}

15 z^{2} - 29 z + 12

40 + 0.1 x = 25 + 0.25 x
