Answer 3

To solve the equations, we'll go through each one step by step:

1. 40 - 5x = 10

Let's isolate the variable x by subtracting 40 from both sides:

-5x = 10 - 40 -5x = -30

Next, divide both sides of the equation by -5 to solve for x:

x = -30 / -5 x = 6

Therefore, the solution to the first equation is x = 6.

2. 60 - 4x = 20

Similarly, let's isolate the variable x by subtracting 60 from both sides:

-4x = 20 - 60 -4x = -40

Divide both sides of the equation by -4:

x = -40 / -4 x = 10

So the solution to the second equation is x = 10.

3. 20 - 2x = 10

Subtract 20 from both sides:

-2x = 10 - 20 -2x = -10

Divide both sides by -2:

x = -10 / -2 x = 5

Therefore, the solution to the third equation is x = 5.

In summary: First equation: x = 6 Second equation: x = 10 Third equation: x = 5
