Answer 3

To solve the equation 2 • (7x - 12) = (5 + 3/4x) • 4, follow these steps:

Step 1: Distribute the multiplication on both sides of the equation.

On the left side: 2 • (7x - 12) = 2 • 7x - 2 • 12 = 14x - 24

On the right side: (5 + 3/4x) • 4 = 4 • 5 + 4 • (3/4x) = 20 + 3x

Step 2: Now, the equation becomes: 14x - 24 = 20 + 3x

Step 3: Move all the x terms to one side of the equation by subtracting 3x from both sides:

14x - 3x - 24 = 20 + 3x - 3x 11x - 24 = 20

Step 4: Next, move the constant term to the other side by adding 24 to both sides:

11x - 24 + 24 = 20 + 24 11x = 44

Step 5: Finally, isolate x by dividing both sides by 11:

x = 44 / 11 x = 4

So, the solution to the equation is x = 4.
