Answer 2

It seems like you've provided two mathematical equations:

Equation 1: $2.8 + j + 3.7 = 12.5$ Equation 2: $5.6 - r + 3.8 = 4.4$

Let's solve these equations step by step:

Equation 1: $2.8 + j + 3.7 = 12.5$

Combine the real number terms on the left side: $6.5 + j = 12.5$

Now, subtract 6.5 from both sides to isolate $j$: $j = 12.5 - 6.5 = 6$

So, the solution for $j$ is $6$.

Equation 2: $5.6 - r + 3.8 = 4.4$

Combine the real number terms on the left side: $9.4 - r = 4.4$

Subtract 9.4 from both sides to isolate $r$: $-r = 4.4 - 9.4 = -5$

Multiply both sides by -1 to solve for $r$: $r = 5$

So, the solution for $r$ is $5$.

To summarize: $j = 6$ and $r = 5$ are the solutions for the given equations.
