Answer 2

To solve these equations, you need to isolate the variable x in each equation. Here's how you can do it step by step:

Equation 1: (2x - 7)/3 = 3/9

Step 1: Multiply both sides of the equation by 3 to get rid of the fraction on the left side:

(2x - 7)/3 * 3 = (3/9) * 3

This simplifies to:

2x - 7 = 1

Step 2: Add 7 to both sides of the equation to isolate 2x:

2x - 7 + 7 = 1 + 7

This simplifies to:

2x = 8

Step 3: Finally, divide both sides by 2 to solve for x:

(2x)/2 = 8/2

x = 4

So, the solution to the first equation is x = 4.

Equation 2: (3x - 5)/4 = 2/8

Step 1: Simplify the right side of the equation:

2/8 simplifies to 1/4.

So, the equation becomes:

(3x - 5)/4 = 1/4

Step 2: Multiply both sides of the equation by 4 to get rid of the fraction on the left side:

(3x - 5)/4 * 4 = (1/4) * 4

This simplifies to:

3x - 5 = 1

Step 3: Add 5 to both sides of the equation to isolate 3x:

3x - 5 + 5 = 1 + 5

This simplifies to:

3x = 6

Step 4: Finally, divide both sides by 3 to solve for x:

(3x)/3 = 6/3

x = 2

So, the solution to the second equation is x = 2.

To summarize:

1. The solution to the first equation is x = 4.
2. The solution to the second equation is x = 2.
