simplify 7(x-1/2)

Solution

simplify

7 (x - \frac{1}{2})

\frac{7 ( 2 x - 1 )}{2}

Solution steps

7 (x - \frac{1}{2})

Join

x - \frac{1}{2} : \frac{x \cdot 2 - 1}{2}

= 7 \cdot \frac{x \cdot 2 - 1}{2}

= 7 \cdot \frac{2 x - 1}{2}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{7 ( 2 x - 1 )}{2}

y (5 x + 3 y - 3 z = 0,) (2 x + y - 3 z = 1)

\frac{x - 29}{( x - 4 ) ( x + 1 )}

\frac{1}{( x + 3 ) ( x + 1 )}

(- b + b^{2} - 4 a c)^{2}

\frac{x}{( x ^{2} + k ) ( x ^{2} + b x + c )}
