x=23

Explanation:

Multiplying the given equation by 12

7(x-3)=12/3x+48

7(x-3)=4x+48

since
7(x-3)=7x-21

we get

7x-21=4x+48

Adding 21

7x=4x+69

subtracting 4x

3x=69
so

x=23

x=23

Explanation:

Let's get rid of the fractions so we can just have a plain vanilla linear equation. We can multiply all terms by 12. We get

7(x-3)=4x+48

We can next distribute the 7 to both terms in the parenthesis to get

7x-21=4x+48

Next, we can add 21 to both sides to further isolate the x terms. We will get

7x=4x+69

Subtracting 4x from both sides gives us

3x=69

Lastly, we can divide both sides by 3 to get

x=23

Hope this helps!
