Answer:
a = 0.4 and b=1.6
Step-by-step explanation:
Both expressions are simply divided
(2x + 8y = 60) ÷ (ax + by = 12)
60÷12 = 5, Hence coefficient of x and y in the bigger equation is divided by 5 to find a and b
2/5 = 0.4 = a
8/5= 1.6 = b
Dependent variable. Its fairly easy if you plug in the problem into
