expand-2(-7x+3y=-30)

expand

- 2 (- 7 x + 3 y = - 30)

14 x - 6 y = 60

Solution steps

- 2 (- 7 x + 3 y = - 30)

= - 2 (- 7 x + 3 = y - 30)

Distribute parentheses

(- 2) (- 7 x) + (- 2) \cdot 3 y = (- 2) (- 30)

Apply minus-plus rules

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

2 \cdot 7 x - 2 \cdot 3 y = 2 \cdot 30

Simplify

2 \cdot 7 x - 2 \cdot 3 y = 2 \cdot 30 : 14 x - 6 y = 60

14 x - 6 y = 60

\frac{2 x ^{2} + 8 x + 3}{( x + 1 ) ^{3}}

(x + 1) \cdot ln (x + 1)

(n + 1) (n - 1)!

\frac{8 e ^{8 x} ( 4 x + 1 )}{45}

- x - 4 (- 7 - 4 x = 103)
