Question

Three blankets and a sheet cost me RM190. Two sheets and a blanket cost a total of RM100. Find the cost of one blanket and one sheet

Answer 1

Explanation:

x is one blanket

y in one sheet

3x+y=190

2y+x=100

y=190-3x

2y+x=100

replace the y in the second equation with the first one

2(190-3x)+x=100

380-6x+x=100

380-5x=100

-5x=100-380

-5x=-280

x= -280/-5

x=56

replace the x with 56 so you can find the y

2y+56=100

2y=100-56

2y=44

y=44/2

y=22

so one blanket is 56 and a sheet is 22
