Question

1.
-5 x (1 + 2y) - 8 x (-4 + 5y)

2.
-5 x (y + 2) + 5 x (y -5)

Answer 1

Answer:

1.(27-50y)

2.(-35)

Step-by-step explanation:

1. -5(1+2y)-8(-4+5y)

= -5-10y+32-40y

= 27-50y

2.-5(y+2)+5(y-5)

= -5y-10+5y-25

= -35

Answer 2

Answer:

1. y = 37/-50

2. y = 35

Step-by-step explanation:

1.

-5 x (1 + 2y) - 8 x (-4 + 5y)

-5 - 10y - 32 - 40y = 0

- 50y = 37

y = 37/-50

2.

-5 x (y + 2) + 5 x (y -5)

- 5y - 10 + 5y - 25 = 0

y = 35
