The cost of 1 cherry pie + 1 blueberry pie equals $22. 7 cherry pies plus 6 bluberry pies equals $140. How much is each pie cherry an blueberry?

let cost of cherry pie be x and blueberry be yso, x + y = 22and 7x + 6y =140from first equation x = 22 -yplugging the value of x in the second equation we get7(22-y) +6y = 140154 - 7y +6y = 140-y = -14y = 14and x = 22-14 = 8so, cost of each cherry pie is $8 and cost of each blueberry is $8Thanks :)
