What is the value of x if 3x + 5 = 20? (2020)

What is the value of x if 3x + 5 = 20? (2020)

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: Calculate the right side: 20 - 5 equals 15. Now the equation is 3x = 15.
Step 4: Next, to find the value of x, divide both sides of the equation by 3. This gives you x = 15 / 3.
Step 5: Calculate the division: 15 divided by 3 equals 5. So, x = 5.
