Question

Find the value of Y in each of the following equations :

1. 2Y + 20Y = 20Y + 40
2. 2Y - 10 + 20 = 20Y + 40
3. 2Y - 8 - 10 = 20Y + 40
4. 2y + 10 + 10 = 20Y + 40
5. 2y + 20 - 20 = 20Y + 40

Answer 1

Step-by-step explanation:

2Y+20Y-20Y=40

2Y=40

Y=20

2Y-20Y=40+10-20

2Y-20Y=50-20

-18Y=30

Y=-5/3

2Y-20Y=40+10+8

2Y-20Y=58

-18Y=58

Y=-29/9

2Y-20Y=40-20

-18Y=20

Y=-10/9

2Y-20Y=40-20+20

-18Y=40

Y=-20/9
