[AI-generated answer — Bot GPT 3.5]

The equation "1.3x + 2 = 8" is false.

Answer 2

[AI-generated answer — Step-by-Step Bot]

To determine which equation is false, we can substitute different values for x and see if the equation holds true.

1. For the equation 1.3x + 2 = 8:
Subtracting 2 from both sides gives us: 1.3x = 6
Dividing both sides by 1.3 gives us: x ≈ 4.615

Substituting x = 4.615 into the equation:
1.3(4.615) + 2 = 5.9995 + 2 ≈ 7.9995

Therefore, the equation 1.3x + 2 = 8 is true.

2. For the equation 22x - 5 = 10:
Adding 5 to both sides gives us: 22x = 15
Dividing both sides by 22 gives us: x ≈ 0.682

Substituting x = 0.682 into the equation:
22(0.682) - 5 = 15.004 - 5 ≈ 10.004

Therefore, the equation 22x - 5 = 10 is true.

Since both equations are true, neither of them is false.

Answer 3

To determine which equation is false, we need to solve each equation and check if they satisfy the given conditions. Let's analyze both equations:

1) 1.3x + 2 = 8

Subtracting 2 from both sides, we get:
1.3x = 6

Dividing both sides by 1.3:
x = 4.615

Now, let's substitute this value of x into the equation and check if it satisfies the condition:
1.3(4.615) + 2 = 8
6.0005 + 2 = 8
8.0005 ≠ 8

Therefore, the equation 1.3x + 2 = 8 is false.

2) 22x - 5 = 10

Adding 5 to both sides, we get:
22x = 15

Dividing both sides by 22:
x = 0.682

Now, let's substitute this value of x into the equation and check if it satisfies the condition:
22(0.682) - 5 = 10
14.964 - 5 = 10
9.964 ≠ 10

Therefore, the equation 22x - 5 = 10 is false as well.

In conclusion, both equations given are false since neither equation satisfies the given conditions.
