Answer 3

To solve the equation, we need to isolate the variable x on one side of the equation. Follow these steps:

Step 1: Simplify the equation. Step 2: Isolate the term with x. Step 3: Solve for x.

Let's go through each step:

Step 1: Simplify the equation. To simplify the equation, perform the multiplication first:

x + 7 * 4 = 40

Step 2: Isolate the term with x. Subtract 7 * 4 from both sides of the equation to isolate the x term:

x = 40 - 28

Step 3: Solve for x. Now, perform the subtraction:

x = 12

So, the solution to the equation is x = 12.
