Sure, here's a math problem solved in English with a detailed explanation:

Problem: Solve the equation 3x + 4 = 19.

Solution: To solve for x, we first subtract 4 from both sides of the equation to isolate the term with x:

3x + 4 - 4 = 19 - 4 3x = 15

Now, to find the value of x, we divide both sides of the equation by 3:

3x / 3 = 15 / 3 x = 5

So, the solution to the equation 3x + 4 = 19 is x = 5. This means that when we substitute x with 5 in the original equation, the equation becomes true:

3(5) + 4 = 15 + 4 15 + 4 = 19 19 = 19

The equation holds true, confirming that x = 5 is the correct solution.
