Q
Q: If 5x + 3 = 18, what is the value of x?
Solution:
5x = 18 - 3 = 15, so x = 15/5 = 3.
Steps: 5
Show Steps
Step 1: Start with the equation 5x + 3 = 18.
Step 2: To isolate the term with x, subtract 3 from both sides of the equation. This gives you 5x = 18 - 3.
Step 3: Calculate 18 - 3, which equals 15. Now the equation is 5x = 15.
Step 4: To find the value of x, divide both sides of the equation by 5. This gives you x = 15 / 5.
Step 5: Calculate 15 divided by 5, which equals 3. Therefore, x = 3.
