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 $10$ and $7$ .

Steps

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

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

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

Step 4 ：Divide both sides of the equation $3 x = 21$ 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 $10$ and $7$ .
