Question

Y=1/3x+2 and y=2/3x-1

Answer 1

The value of x and y is 9, 5.

Explanation:

`\ The \ Given \ value:\\\\y=(1)/(3)x+2........................(i)\\\\ y= (2)/(3)x-1 ..........................(ii)\\\\`

first we subtract the equation (i) to (ii)...

`y=(1)/(3)x+2 \\\\y= (2)/(3)x-1\\\\0 = (1)/(3) x- (2)/(3)x + 2+1 \\\\-3= (1-2)/(3) x\\\\-3 = - (1)/(3)x\\\\ (1)/(3) x= 3 \\\\x=9\\\\`

Put the value of x in equation (i) ...

equation (i)

`y= (1)/(3) x+2\\\\y= (1)/(3) * 9+2\\\\y= 3+2\\\\y=5\\`
