Q
Q: What is the value of x in the equation 3x - 5 = 7?
Solution:
Solving for x: 3x = 12, thus x = 4.
Steps: 5
Show Steps
Step 1: Start with the equation 3x - 5 = 7.
Step 2: Add 5 to both sides of the equation to get rid of -5. This gives you 3x = 7 + 5.
Step 3: Simplify the right side. 7 + 5 equals 12, so now you have 3x = 12.
Step 4: Now, divide both sides of the equation by 3 to solve for x. This gives you x = 12 / 3.
Step 5: Simplify 12 / 3, which equals 4. So, x = 4.
