Please don’t give pictures for this one!
1) x-y = 197.79
71y=69x-1999

Answer 1

Step-by-step explanation:

X - Y = 197.79 -----------(1)

71Y = 69X - 1999 ----------(2)

From equation (1) , we get

X - Y = 197.79

X = 197.79 + Y --------(3)

Putting the value of X in equation (2), we get

71Y = 69X - 1999

71Y = 69 ( 197.79 - 1999 )

71Y = 69 ( -1801.21 )

71Y = -11648.51

Y = 164.06 ( approx )

Putting the value of Y in equation (3) , we get

X = 197.79 + Y

X = 197.79 + 164.06

X = 361.85 ( approx )
