Question

1)The equations 2x+ 3y = 7 and 4x - 3y =1 have

2)HCF(320, x) = 20, LCM(320, x) = 2240, then x =

3)If the graphs of the equations 2x + 3y =1 and kx +y =4 intersect at a point,

Answer 1

Answer:

2x+3y=7

4x-3y=1

6x=8

x=8/6

x=4/3

put the value of x in equation i

2x+3y=7

2×4/3+3y=7

8/3+3y=7

3y=7-8/3

3y=21-8/3=13/3

y=13/3×3/1

y=13

x=4/3

y=13
