Two dozen eggs and a loaf of bread cost k4.82 . Half a dozen eggs and two loaves of bread cost k2.29. Find the cost of a loaf of bread.
Let the cost of one dozen eggs be x, and one loaf of bread be y.

2%2Ax+%2B+y+=+4.82 ----> (1)
0.5%2Ax+%2B+2%2Ay+=+2.29 ----> (2)

Multiplying (2) by 4, to eliminate x,

2%2Ax+%2B+8%2Ay+=+9.16 -----> (3)

Subtracting (1) from (3),

7*y = 4.34 ----> (4)
y = 4.34/7 = 0.62k

Cost of a loaf of bread = highlight%280.62%29k

Hope this helps :)
