Answer 3

To solve the given equation $0.4(x-3) + 2.5 = 0.5(4+x)$, we'll follow these steps:

1. Distribute the constants inside the parentheses.
2. Simplify and solve for $x$.

Let's start with step 1:

$0.4(x-3) + 2.5 = 0.5(4+x)$

Distribute the constants:

$0.4x - 1.2 + 2.5 = 2 + 0.5x$

Now, let's simplify and solve for $x$:

$0.4x - 1.2 + 2.5 = 2 + 0.5x$

Combine the constants:

$0.4x + 1.3 = 2 + 0.5x$

Move the $0.5x$ term to the left side and the constant terms to the right side:

$0.4x - 0.5x = 2 - 1.3$ $0.1x = 0.7$

Now, isolate $x$ by dividing both sides by $0.1$:

$x = \frac{0.7}{0.1}$ $x = 7$
