expand-7(3-3x=-3(-2x+5))

expand

- 7 (3 - 3 x = - 3 (- 2 x + 5))

- 21 + 21 x = - 42 x + 105

Solution steps

- 7 (3 - 3 x = - 3 (- 2 x + 5))

= - 7 (3 - 3 = x - 3 (- 2 x + 5))

Distribute parentheses

= (- 7) \cdot 3 + (- 7) (- 3 x =) + (- 7) (- 3 (- 2 x + 5))

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

- 7 \cdot 3 + 7 \cdot 3 x = 7 \cdot 3 (- 2 x + 5)

Simplify

- 7 \cdot 3 + 7 \cdot 3 x = 7 \cdot 3 (- 2 x + 5) : - 21 + 21 x = - 42 x + 105

- 21 + 21 x = - 42 x + 105

- (a + b = 5)

\frac{144 ( 13 x + 10 )}{13}

(3 f + 2 g = 5,) (f - g = 1)

(4 x - 5, x^{2} + 4) (x)

\frac{( x - 1 ) e ^{2 x}}{2}
