Answer 3

Let's solve each equation step by step:

1. 4x = 100 To isolate x, we divide both sides of the equation by 4: 4x/4 = 100/4 x = 25

So the solution for equation 1 is x = 25.

2. 10x + 10 = 100 To isolate x, we first subtract 10 from both sides of the equation: 10x + 10 - 10 = 100 - 10 10x = 90

Next, we divide both sides of the equation by 10: 10x/10 = 90/10 x = 9

So the solution for equation 2 is x = 9.

3. 5x = 20 To isolate x, we divide both sides of the equation by 5: 5x/5 = 20/5 x = 4

So the solution for equation 3 is x = 4.

4. 4x + 4 = 20 To isolate x, we first subtract 4 from both sides of the equation: 4x + 4 - 4 = 20 - 4 4x = 16

Next, we divide both sides of the equation by 4: 4x/4 = 16/4 x = 4

So the solution for equation 4 is x = 4.

5. 15x = 3000 To isolate x, we divide both sides of the equation by 15: 15x/15 = 3000/15 x = 200

So the solution for equation 5 is x = 200.

6. 20x + 2000 = 3000 To isolate x, we first subtract 2000 from both sides of the equation: 20x + 2000 - 2000 = 3000 - 2000 20x = 1000

Next, we divide both sides of the equation by 20: 20x/20 = 1000/20 x = 50

So the solution for equation 6 is x = 50.

To summarize:

1. x = 25
2. x = 9
3. x = 4
4. x = 4
5. x = 200
6. x = 50
