To solve this equation, let's break it down step by step.
Let's call the difference "d".
"4 times the difference" can be written as 4d.
The phrase "and 7 is 12" means that when we add 7 to the previous sum (4d), we get 12.
So, the equation can be written as: 4d + 7 = 12.
To solve for d, we need to isolate it on one side of the equation.
Subtracting 7 from both sides of the equation, we get: 4d = 5.
Finally, to solve for d, divide both sides of the equation by 4: d = 5/4.
Therefore, the difference (d) is 5/4.
