x = 18.25
y = 15.25
Step-by-step explanation:
System of Equations:
Solve:
3x + 5y = 131 [1]
6x + 2y = 140 [2]
Multiplying [1] by -2:
-6x - 10y = -262 [3]
Adding [2] and [3]:
-8y = -122
y = -122/(-8)=15.25
y = 15.25
Substituting in [1]
3x + 5(15.25) = 131
3x + 76.25 = 131
3x = 54.75
x = 54.75/3
x = 18.25
Thus:
x = 18.25
y = 15.25
