What is the value of x in the equation 3x + 7 = 22? (2020)

What is the value of x in the equation 3x + 7 = 22? (2020)

Step 1: Start with the equation 3x + 7 = 22.
Step 2: To isolate the term with x, subtract 7 from both sides of the equation. This gives you 3x = 22 - 7.
Step 3: Calculate 22 - 7, which equals 15. Now the equation is 3x = 15.
Step 4: To find the value of x, divide both sides of the equation by 3. This gives you x = 15 / 3.
Step 5: Calculate 15 divided by 3, which equals 5. So, x = 5.
