Answer

The solutions to the equations are $x = 10$ for the first equation and $x = 7$ for the second equation. So, the final answers are $\boxed{10}$ and $\boxed{7}$.

Steps

Step 1 ：Given the equation $2x - 7 = 13$, add 7 to both sides to get $2x = 20$.

Step 2 ：Divide both sides of the equation $2x = 20$ by 2 to get $x = 10$.

Step 3 ：Given the equation $3x + 4 = 25$, subtract 4 from both sides to get $3x = 21$.

Step 4 ：Divide both sides of the equation $3x = 21$ by 3 to get $x = 7$.

Step 5 ：The solutions to the equations are $x = 10$ for the first equation and $x = 7$ for the second equation. So, the final answers are $\boxed{10}$ and $\boxed{7}$.
