Answer 2

Let's solve each of these equations step by step:

1. 4x = 42

To solve for x, you can divide both sides of the equation by 4:

4x/4 = 42/4

x = 10.5

So, the solution for this equation is x = 10.5.

2. 27 - 2x = 10

First, subtract 27 from both sides of the equation:

27 - 27 - 2x = 10 - 27

-2x = -17

Now, divide both sides by -2 to solve for x:

(-2x)/(-2) = (-17)/(-2)

x = 8.5

The solution for this equation is x = 8.5.

3. 6(x - 5) = 63

First, distribute the 6 on the left side of the equation:

6x - 30 = 63

Now, add 30 to both sides to isolate the term with x:

6x - 30 + 30 = 63 + 30

6x = 93

Finally, divide both sides by 6 to find x:

(6x)/6 = 93/6

x = 15.5

So, the solution for this equation is x = 15.5.

The solutions to the three equations are:

1. x = 10.5
2. x = 8.5
3. x = 15.5
