simplify-(x-7y)-2(2y-5x)

simplify

- (x - 7 y) - 2 (2 y - 5 x)

9 x + 3 y

Solution steps

- (x - 7 y) - 2 (2 y - 5 x)

Apply the distributive law:

- (a - b) = - a + b

- (x - 7 y) = - x + 7 y

= - x + 7 y - 2 (2 y - 5 x)

Expand

- 2 (2 y - 5 x) : - 4 y + 10 x

= - x + 7 y - 4 y + 10 x

Add similar elements:

7 y - 4 y = 3 y

= - x + 3 y + 10 x

Group like terms

= - x + 10 x + 3 y

Add similar elements:

- x + 10 x = 9 x

= 9 x + 3 y

\frac{\frac{15 - 3 x}{x + 5}}{\frac{5 x - x ^{2}}{5 x + 1}}

\frac{9 \cdot ( 3 ^{- 2} ) ^{3} \cdot 3 ^{- 3}}{3 ^{- 6} \cdot 3}

\frac{2 lo g _{3} ( 5 )}{lo g _{3} ( 4 )}
