simplify (10x-y+4)-[-(-7x-21+3y)-(-3(-11y+9x-5))]

simplify

(10 x - y + 4) - [- (- 7 x - 21 + 3 y) - (- 3 (- 11 y + 9 x - 5))]

- 24 x + 35 y - 2

Solution steps

(10 x - y + 4) - (- (- 7 x - 21 + 3 y) - (- 3 (- 11 y + 9 x - 5)))

Apply rule:

(a) = a

(10 x - y + 4) = 10 x - y + 4

= 10 x - y + 4 - (- (- 7 x - 21 + 3 y) - (- 3 (- 11 y + 9 x - 5)))

Simplify

- (- (- 7 x - 21 + 3 y) - (- 3 (- 11 y + 9 x - 5))) : - 34 x + 36 y - 6

= 10 x - y + 4 - 34 x + 36 y - 6

Group like terms

= 10 x - 34 x - y + 36 y + 4 - 6

Add similar elements:

10 x - 34 x = - 24 x

= - 24 x - y + 36 y + 4 - 6

Add similar elements:

- y + 36 y = 35 y

= - 24 x + 35 y + 4 - 6

Subtract the numbers:

4 - 6 = - 2

= - 24 x + 35 y - 2

\frac{6 x ^{2}}{x - 1} + \frac{- 6 x}{x - 1}

10 x^{3} - 2 sec^{2} (x)

\frac{e ^{4}}{e ^{- 1} + e ^{- 2}}

(448)^{3}

\frac{5 x + 3 y}{2 ( x + y )} - \frac{3 x - 5 y}{8 ( x + y )}
