Q
Q: If 3x + 5 = 20, what is the value of x?
Solution:
To solve for x, subtract 5 from both sides: 3x = 15. Then divide by 3: x = 5.
Steps: 5
Show Steps
Step 1: Start with the equation 3x + 5 = 20.
Step 2: To isolate the term with x, subtract 5 from both sides of the equation. This gives you 3x = 20 - 5.
Step 3: Simplify the right side. 20 - 5 equals 15, so now you have 3x = 15.
Step 4: Now, to find the value of x, divide both sides of the equation by 3. This gives you x = 15 / 3.
Step 5: Simplify the division. 15 divided by 3 equals 5, so x = 5.
