Twenty - four is divided into two parts such that 7 times the first part added to 5 times the second part makes 146 . Find each part
Let first part be x
2nd part= 24-x
7x + 5(24-x) = 146
7x+120-5x = 146
7x-5x +120 = 146
2x+120 = 146
2x = 146-120 = 26
x= 26/2 = 13
1st part = 13
2nd part = 24-x
=24-13 = 11
hope it helps
Best wishes!
