expand 3(-7x+4y=-8)

expand

3 (- 7 x + 4 y = - 8)

- 21 x + 12 y = - 24

Solution steps

3 (- 7 x + 4 y = - 8)

= 3 (- 7 x + 4 = y - 8)

Distribute parentheses

3 (- 7 x) + 3 \cdot 4 y = 3 (- 8)

Apply minus-plus rules

+ (- a) = - a

- 3 \cdot 7 x + 3 \cdot 4 y = - 3 \cdot 8

Simplify

- 3 \cdot 7 x + 3 \cdot 4 y = - 3 \cdot 8 : - 21 x + 12 y = - 24

- 21 x + 12 y = - 24

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

cos (y (e^{x + z} - 1))

7 (l - 3 = 49)
