To determine which equation is false, let's solve both equations and see which one results in a contradiction.

1) 1.3x + 2 = 8

Subtract 2 from both sides:

1.3x = 6

Divide both sides by 1.3:

x = 6/1.3 ≈ 4.615

2) 22x - 5 = 10

Add 5 to both sides:

22x = 15

Divide both sides by 22:

x = 15/22 ≈ 0.682

From the calculations, it is clear that the first equation (1.3x + 2 = 8) is false because the solution for x is approximately 4.615, not 4.615 as stated in the equation. Therefore, the false equation is 1.3x + 2 = 8.

To determine which equation is false, you need to solve both equations and evaluate if they are true or false.

Let's start with the first equation: 1.3x + 2 = 8

To solve this equation, we need to isolate the variable x.

First, we can subtract 2 from both sides:
1.3x = 8 - 2
1.3x = 6

Next, we divide both sides by 1.3 to find the value of x:
x = 6 / 1.3
x ≈ 4.615

Now, let's check the second equation: 22x - 5 = 10

To solve this equation, we need to isolate the variable x.

First, we can add 5 to both sides:
22x = 10 + 5
22x = 15

Next, we divide both sides by 22 to find the value of x:
x = 15 / 22
x ≈ 0.682

Upon solving both equations, we find the values of x. Now, we can substitute these values back into the original equations to check if they hold true.

1.3(4.615) + 2 = 8
6.00015 ≈ 8

22(0.682) - 5 = 10
10 = 10

Therefore, the first equation is false (1.3x + 2 = 8), while the second equation is true (22x - 5 = 10).
