Question

by cross mthod multiplication 2x-y=6andx-y=2​

Answer 1

Answer:

Step-by-step explanation:

2 X-Y = 6............(1)

X - Y = 2..............(2)

(1)/(2)

(2 X-Y)/(X-Y) = 6/2

(2 X-Y)/(X -Y) = 3             [ CROSS MULTIPLYING]

( 2 X-Y ) = 3(X-Y)

(2 X-Y) = 3 X- 3 Y

- Y + 3Y = 3 X-2X

2 Y = X

SUBSTITUTING IN (2)

2 Y- Y = 2

Y = 2.

X = 2Y =2*2 = 4

THEREFORE,

Y = 2

X = 4 .
