Question

Pls tell me the answer.​

Answer 1

1. x = (4x +40) / 5

5x/ 5 - 4x / 5 = 40 /5

x/ 5 = 40 /5

x. = 40

2. 2x + 3 / 3 = 7x + 45 / 15

15(2x+ 3.) = 21 x + (3×45)

30 x - 21 x. = 90

9 x. = 90

x. = 10

3.

2y + 5/3 = 26 /3 - y

6y + 5 / 3 = 26 - 3y / 3

18 y + 15 = 78 - 9 y

27 y. = 63

y = 7/3

4 3m = 25 m - 8 / 5

15 m = 25 m - 8

10 m = 8

m = 8/10
