Answer 1

Answer:

1. x= 73/21
2. y=2730

Step-by-step explanation:

question✒8x +y=34;x+8y=53....solve it by elimination method

to find✒x and y

*****solution ----*****

8x+y=34---------(1)

☢✒Multiply the first equation by 8

✏8 * (8x + y) = 8 * 34

✏64x + 8y = 272----------(2)

✏ x+8y=53-------------(3)

_______________________

(2)-(3)===>

✏(64x+8y)-(x+8y)=272-53

✏64x+8y-x-8y=219

✏63x=219

✏x=219/63

✏x =73/21

☢value of x put in(3)

✏x+8y=53

✏8y=53-{73/21}

✏8y=1113-73/21

✏8y=1040/21

✏y=1040/8×21

✏y=2730
