expand-1(2x+y=7)

Solution

expand

- 1 (2 x + y = 7)

Solution

- 2 x - y = 7

Solution steps

- 1 \cdot (2 x + y = 7)

= - 1 \cdot (2 x + 7 = y)

Apply the distributive law:

a (b + c) = ab + a c

a = - 1, b = 2 x, c = y = 7

- 1 \cdot 2 x + (- 1) y = 7

Apply minus-plus rules

+ (- a) = - a

- 1 \cdot 2 x - 1 \cdot y = 7

Expand

- 1 \cdot 2 x - 1 \cdot y : - 2 x - y

- 2 x - y = 7
