Answer 2

To solve the equation, we need to follow the order of operations (PEMDAS/BODMAS) and isolate the variable "x" on one side of the equation. Here's the step-by-step solution:

1. Distribute the 4 to both terms inside the parentheses: 4(1,2x + 3,7) = 4 * 1,2x + 4 * 3,7 = 4,8x + 14,8

2. Now the equation becomes: 4,8x + 14,8 - 2,8 = 5,2x

3. Next, combine the constant terms on the left side of the equation: 4,8x + (14,8 - 2,8) = 5,2x 4,8x + 12 = 5,2x

4. To isolate "x," we need to get all the "x" terms on one side and the constants on the other side. Let's move the 4,8x to the right side by subtracting it from both sides of the equation:

   4,8x - 4,8x + 12 = 5,2x - 4,8x

   The 4,8x terms cancel out on the left side, and we have:

   12 = 0,4x

5. Now, to solve for "x," divide both sides by 0,4:

   12 / 0,4 = 0,4x / 0,4

   30 = x

So, the value of "x" that satisfies the equation is x = 30.
