expand (-x+y=2,)(x+3y=-8)

expand

(- x + y = 2,) (x + 3 y = - 8)

- xx - 3 x y = 8 x + y = 2, x + y = 2, 3 y = - y = 2, 8

Solution steps

(- x + y = 2,) (x + 3 y = - 8)

= (- x + 2 =, y) (x + 3 = y - 8)

Distribute parentheses

(- x) x + (- x) \cdot 3 y = (- x) (- 8) + y = 2, x + y = 2, 3 y = y = 2, (- 8)

Apply minus-plus rules

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

- xx - 3 x y = 8 x + y = 2, x + y = 2, 3 y = - y = 2, 8

d x (3 x^{2} y + 2 x)

(2 y^{'} (x) - 4) (y + 2 x)

(x - 6) (x + 7)^{''}

20 sin (30 (n - 3)) + 12
