Answer:

The solution to the system is:

(x, y) = (-1, 1)

Step-by-step explanation:

Given the system of equations:

5x + 10y = 5 ..............................................................(1)

-13x + 4y = 17 ............................................................(2)

From (1)

5x = 5 - 10y

x = 1 - 2y .................................................................(3)

Substituting (3) into (2)

-13(1 - 2y) + 4y = 17

-13 + 26y + 4y = 17

Collect like terms

26y + 4y = 17 + 13

30y = 30

y = 30/30 = 1 .........................................................(4)

Substituting (4) into (3)

x = 1 - 2(1)

x = 1 - 2 = -1

Therefore the solution to the system is:

(x, y) = (-1, 1)
