Marks
2x + 3y = 53
3x - y = 19
Work out the values of x and y.

Answer 1

Answer:

2x+3y=53eq1

3x-y=19eq2

or,-y=19-3x

or,y=19-3x

keeping value of y in eq 1

2x+3y=53

or,2x+3(3x-19)

or2x+19-57=53

or,11x=53+57

or,11x=110

or,x=110\11

=10

againputting the value of x in eq1

2x+3y=53

or,20+3Y=53

or,3y=53-20

or,y=33\3

or,Y=11
