Answer:
(-3,1)
Explanation:
20x = -58 - 2y
17x = -49 - 2y
I will use elimination to solve this system of equations
Multiply the second equation by -1
-1* 17x = -1 *(-49 - 2y)
-17x = -49 +2y
Add the first equation and the modified second equation
20x = -58 - 2y
-17x = +49 +2y
-----------------------
3x = -9
Divide each side by 3
3x/3 = -9/3
x=-3
But we still need to find y
17x = -49 -27
17*-3 =-49 -2y
-51 = -49 -2y
Add 49 to each side
-51+49 = -49+49 -2y
-2 = -2y
Divide by -2
-2/-2 = -2y/-2
1 =y
