Answer 3

To solve for x in the equation $4.7x - (2.5x + 12.4) = 1.9$, follow these steps:

Step 1: Distribute the negative sign to the terms inside the parentheses: $4.7x - 2.5x - 12.4 = 1.9$.

Step 2: Combine like terms on the left side of the equation: $2.2x - 12.4 = 1.9$.

Step 3: Add 12.4 to both sides of the equation to isolate the $2.2x$ term: $2.2x = 1.9 + 12.4$, $2.2x = 14.3$.

Step 4: Divide both sides by 2.2 to solve for x: $x = \frac{14.3}{2.2}$, $x \approx 6.5$.

So, the solution to the equation $4.7x - (2.5x + 12.4) = 1.9$ is $x \approx 6.5$.
