An equation is formed when two equal expressions. The value of x is 24 and Jake made a mistake in step 2. The correct option is A.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The given equation 1/3x + 7 = 15 can be solved as shown below.
Step 1.) 1/3x + 7 = 15
Step 2.) Subtract 7 from both the sides of the equation,
1/3x + 7 - 7 = 15 - 7
Step 3.) 1/3x = 8
Step 4.) Multiply both the sides of the equation by 3,
3 • 1/3x = 3 • 8
Step 5.) x = 24
Hence, the value of x is 24. And Jake made a mistake in step 2.
