expand 7(-4x+9y=28)

expand

7 (- 4 x + 9 y = 28)

- 28 x + 63 y = 28

Solution steps

7 (- 4 x + 9 y = 28)

= 7 (- 4 x + 9 \cdot 28 = y)

Apply the distributive law:

a (b + c) = ab + a c

a = 7, b = - 4 x, c = 9 y = 28

7 (- 4 x) + 7 \cdot 9 y = 28

Apply minus-plus rules

+ (- a) = - a

- 7 \cdot 4 x + 7 \cdot 9 y = 28

Expand

- 7 \cdot 4 x + 7 \cdot 9 y : - 28 x + 63 y

- 28 x + 63 y = 28
