12 apples

12 apples and 2 loaves of bread cost 5.76 and 6 apples and 3 loaves of bread cost 7.68. How much is a loaf of bread?

Correct answer:

a =  0.08
b =  2.4

Step-by-step explanation:


12a + 2b = 5.76
6a + 3b = 7.68

12•a + 2•b = 5.76
6•a + 3•b = 7.68

12a+2b = 5.76
6a+3b = 7.68

a = 2/25 = 0.08
b = 12/5 = 2.4
