Question

solve for x and y
plz help me
and no wrong answers please​

Answer 1

Answer:

let x-1 be u and y-2 be v

so, x=4 and y=4

Answer 2

Answer:

let x-1 be p and y-2 be q

therfore equation will be

5p+q=2-----(1) & 6p-2q=1------(2)

multiply eq (1) by 2

=> 10p +2q=4 ---(3)

add equation 2 &3 we get

10p +2q=4

6p -2q =1

___________

16p =5

p =5/16

put value of p in eq 2)

6(5/16) -2q=1

30/16 -2q =1

15/8 -2q =1

15-16q/8 = 1

-16q = 8 -15

-16q = -7

q = 7/16

but we have let p = x-1

5/16 = x-1

x= 5/16+1

× = 5+16/16

× = 21/6 = 7/2

also q = y-2

7/16 =y-2

y= 7/16 +2

y = 7+32/16

y = 39/16

hope this will help you
