Answer

$\boxed{x = 3}$ is the solution to the equation $2 \cdot(x+5)-3 \cdot(5-x)=10$ in the universe of rational numbers

Steps

Step 1 ：Given the equation $2 \cdot(x+5)-3 \cdot(5-x)=10$

Step 2 ：First, distribute the 2 and -3 into the parentheses to get $2x + 10 - 15 + 3x = 10$

Step 3 ：Simplify the equation to get $5x - 5 = 10$

Step 4 ：Add 5 to both sides of the equation to get $5x = 15$

Step 5 ：Finally, divide both sides by 5 to solve for x, which gives us $x = 3$

Step 6 ：$\boxed{x = 3}$ is the solution to the equation $2 \cdot(x+5)-3 \cdot(5-x)=10$ in the universe of rational numbers
