Answer: (x = 6, y = -0.5)

Explanation:

Substitute into one of the equations: 3(5 - 2y) + 2y = 17

Apply Multiplicative Distribution Law: 15 - 6y + 2y = 17

Rearrange unknown terms to the left side of the equation: -6y + 2y = 17 - 15

Combine like terms: -4y = 2

Divide both sides of the equation by the coefficient of variable: y = 2 / (-4)

Remove the parentheses: y = -2 / 4

Calculate the product or quotient: y = -0.5

Substitute into one of the equations: x = 5 - 2 * (-0.5)

Remove the parentheses: x = 5 - 2 * -0.5

Calculate the product or quotient: x = 5 + 1

Calculate the sum or difference: x = 6

The solution of the system is: {x = 6, y = -0.5}

Hope this helps!
