expand (5x+2y=8,)(2x-4y=-8)

expand

(5 x + 2 y = 8,) (2 x - 4 y = - 8)

5 \cdot 2 xx - 5 \cdot 4 x y = - 5 \cdot 8 x + 2 y = 8, 2 x - 2 y = 8, 4 y = - 2 y = 8, 8

Solution steps

(5 x + 2 y = 8,) (2 x - 4 y = - 8)

= (5 x + 2 \cdot 8 =, y) (2 x - 4 = y - 8)

Distribute parentheses

5 x \cdot 2 x + 5 x (- 4 y =) + 5 x (- 8) + 2 y = 8, 2 x + 2 y = 8, (- 4 y =) + 2 y = 8, (- 8)

Apply minus-plus rules

+ (- a) = - a

5 \cdot 2 xx - 5 \cdot 4 x y = - 5 \cdot 8 x + 2 y = 8, 2 x - 2 y = 8, 4 y = - 2 y = 8, 8

(e^{x} - e^{- x})^{4}
