Answer :

We start with the equation:
[tex]$$4x + 7 = 15.$$[/tex]

Step 1: Subtract 7 from both sides

Subtracting 7 from each side gives:
[tex]$$4x = 15 - 7,$$[/tex]
which simplifies to
[tex]$$4x = 8.$$[/tex]

Step 2: Divide both sides by 4

Dividing both sides by 4 to solve for [tex]$x$[/tex], we have:
[tex]$$x = \frac{8}{4}.$$[/tex]
Simplifying the fraction:
[tex]$$x = 2.$$[/tex]

Thus, the solution to the equation is:
[tex]$$x = 2.$$[/tex]
