Answer 1

1. 1/2×+1/3×=5

3x + 2x = 30

5x = 30

x = 6

2. ×/4=2×/5+3

5x = 8x + 60

5x - 8x = 60

-3x = 60

x = -20

3. 4×+5/8=3/2

2 (4x + 5) = 24

4x + 5 = 12

4x = 12 - 5

4x = 7

x = 7/4

4. 3/2=24/×

3x = 48

x= 16

5. 3×-8/5=8×-5/10

10(3x - 8)= 5 (8x-5)

30x - 80 = 40x - 25

30x - 40x = -25 + 80

-10x = 55

x = -11/2

6. ×-3/5+×-2/3=×-1/6

6(x-3) + 10 (x-2) = 5(x-1)

6x - 18 + 10x - 20 = 5x - 5

16x - 38 = 5x - 5

16x - 5x = -5 +38

11x = 33

x = 3

7. W/2-w3/5=w-6/2

5w - 6w = 5(w-6)

-w = 5w -30

-w - 5w = -30

-6 w = -30

w = 5

8. 2-3y/7=4y/3

3(2-3y) = 28y

6 - 9y = 28y

-9y - 28y = -6

-37y = -6

y= 6/37
