Question

If x+y=4 and 2x-3y=3 then x-y is

Answer 1

2x - 3y = 3 ••••(1)

2x + 2y = 8••••(2) [Subtract]

_-__-___-___

- 5y = - 5

y = 1

Put above value of y in equ-----(1)

So,

2x - 3×1 = 3

2x = 3+3

x = 3

________________

------------------------------

Then,

x - y = 3 - 1 = 2 ...ans...

Answer 2

Answer:

X-Y=2

Step-by-step explanation:

x+y=4 is equation number 1

2x-3y=3 equation number 2

2*equation number 1=2x+2y=8 this is equation number 3

Equation number 3-

Equation number 2

2x+2y=8-

2x-3y=3

________

0+5y=5

5y=5

Therefor y=5/5=1

X+Y=4

X+1=4

X=4-1=3

VALUE OF X IS 3

VALUE OF Y IS 1

THERE FOR X-Y=3-1=1
