Answer:
Step-by-step explanation:
13x+2y=1
+ 5x-2y=-19
-------------------
18x=18
x=1
5x1-2y=-19
5-2y=-19
-2y=-19-5
-2y=14
-y=7
y=-7
x=1
y=-7
Answer:
x = 6.5 and y = -22.1
Step-by-step explanation:
13x/13 + 2y = 1/13
2y = 13
2y/2 = 13
y = 6.5
5x -2(6.5) = -19
5x (6.5) = -17
5x = -110.5
5x/5 = -110.5/5
x = -22.1
