Answer 1

1) y - 4 = 7. 》》y = 11

2) 5x - 2 = 7

5x = 10

X = 2

3) 5/(X + 1) = 3

5 = 3 (X + 1)

5 = 3X + 3

2 = 3X

2/3 = X

4) (3X - 2) / (X + 1) = 2 / 3

3 (3X - 2) = 2(X + 1)

9X - 6 = 2X + 2

7X = 8

X = 8/7

5) 4X/5 + 8 = 20

4x/5 = 12

4X = 60

X = 15

6) 4X + 9 = 21

4X = 12

X = 3

7) 7X - 41 = -13

7X = 41 - 13

7X = 28

X = 4

8) -3X / 5 + 1 = 4

-3X/5 = 3

-3X = 15

X = -5
