Answer 2

Let's solve the given equations step by step:

1. 8x + 4 = 3x + 4

Subtract 4 from both sides to isolate the x terms:

8x + 4 - 4 = 3x + 4 - 4 8x = 3x

Now, subtract 3x from both sides to get the x term on one side:

8x - 3x = 3x - 3x 5x = 0

Divide both sides by 5 to solve for x:

5x / 5 = 0 / 5 x = 0

So, the solution for the first equation is x = 0.

2. 1/15(x - 5) = 1/3

First, distribute the fraction on the left side:

(1/15) * (x - 5) = 1/3

Multiply both sides by 15 to get rid of the fraction on the left side:

15 * (1/15) * (x - 5) = 15 * (1/3)

The (1/15) on the left side cancels out, leaving:

x - 5 = 5

Now, add 5 to both sides to isolate the x term:

x - 5 + 5 = 5 + 5 x = 10

So, the solution for the second equation is x = 10.

To summarize:

1. 8x + 4 = 3x + 4 has a solution of x = 0.
2. 1/15(x - 5) = 1/3 has a solution of x = 10.
