expand (-2x-2y=1,2)(-8x-y=-15)

expand

(- 2 x - 2 y = 1, 2) (- 8 x - y = - 15)

2 \cdot 8 xx + 2 x y = 2 \cdot 15 x + 2 y = 1, 2 \cdot 8 x + 2 y = 1, 2 y = 2 y = 1, 2 \cdot 15

Solution steps

(- 2 x - 2 y = 1, 2) (- 8 x - y = - 15)

= (- 2 x - 2 \cdot 1 \cdot 2 =, y) (- 8 x - = y - 15)

Distribute parentheses

= (- 2 x) (- 8 x) + (- 2 x) (- y =) + (- 2 x) (- 15) + (- 2 y = 1, 2) (- 8 x) + (- 2 y = 1, 2) (- y =) + (- 2 y = 1, 2) (- 15)

Apply minus-plus rules

(- a) (- b) = ab

2 \cdot 8 xx + 2 x y = 2 \cdot 15 x + 2 y = 1, 2 \cdot 8 x + 2 y = 1, 2 y = 2 y = 1, 2 \cdot 15

(- 3 \cdot + y) (\cdot + 2 y)

(a (b c - d e)^{2}) r

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

- e^{x} (1 + e^{x})

\frac{( x + y ) ^{9}}{( x - y ) ^{5}}
