Question

solve this by elimination method
1. 5-(3y-1)=y-4
2. 8 (d-1) + 17 (d-3) =5 (4d-4) + 5​

Answer 1

Answer:

1. y = 2

1. d = 8.8

Step-by-step explanation:

1. 5 - ( 3y - 1 ) = y - 4

5 -3y - 1 = y - 4

4 - 3y = y - 4

-3y - y = -4 - 4

-4y = -8

-y = -8/4

-y = -2

y = 2

2. 8(d - 1) + 17(d - 3) =5(4d - 4) + 5

8d - 8 + 17d - 51 = 20d - 20 + 5

25d - 59 = 20d - 15

25d - 20d = 59 - 15

5d = 44

d = 44/5

d = 8.8
