expand 7a(x+y-1)-3b(x+y-1)

expand

7 a (x + y - 1) - 3 b (x + y - 1)

7 a x + 7 a y - 7 a - 3 b x - 3 b y + 3 b

Solution steps

7 a (x + y - 1) - 3 b (x + y - 1)

Expand

7 a (x + y - 1) : 7 a x + 7 a y - 7 a

= 7 a x + 7 a y - 7 a - 3 b (x + y - 1)

Expand

- 3 b (x + y - 1) : - 3 b x - 3 b y + 3 b

= 7 a x + 7 a y - 7 a - 3 b x - 3 b y + 3 b
