Answer:
Step-by-step explanation:
If 3x + 4 = 25, the first step for solving for x will be to subtract 4 from both sides of the equation. This gives us 3x + 4 - 4 = 25 - 4, or 3x + 0 = 21, or 3x = 21. Now take 21 (from the right side of the equation) and divide by 3 (from the left side of the equation) to come up with x = 7.
