Question

Here is a diagram and its corresponding equation. Find the solution to the equation.

Answer 1

Answer:

The solution to the equation is:

• x = 2.5 or x = 5/2

Step-by-step explanation:

To find the solution to the equation, you only must operate the equation until you clear the x variable, with the next steps:

• Equation: 4(x+7) = 38

And we solve:

• 4x + 28 = 38 (we multiply 4 by x and 7)
• 4x = 38 - 28 (we pass the +28 to subtract to the right side of the equality and operate)
• x = 10 / 4 (we pass the 4 that is multiplying to divide to the right side of the equality)
• x = 2.5 (we divide)

As you can see, the solution of the equation is x = 2.5 or x = 5/2
