Answer:
Step-by-step explanation:
Answer:
x = 8, y = 3.
Step-by-step explanation:
11x − 20y = 28
3x + 4y = 36 multiply this equation by 5:
15x + 20y = 180
Add this new equation to the first one ( to eliminate the 20y):
26x = 208
x = 208/26 = <em> </em>8.
Substitute x = 8 into the second equation:
3(8) + 4y = 36
4y = 36 - 24 = 12
y = 3.
