Hi ,

i ) pi ×x + 3 y = 25

3y = 25 - pi× x

y = ( 25 - pi × x )/ 3

y = 25/3 - pi × x /3

ii )
If x = 7

y = 25/ 3 - ( 22/ 7 )× ( 7/3)

y = 25/3 - 22 /3

y = ( 25 - 22 )/3

y = 3/3

y = 1

ii) if x = - 7

y = 25/3 - ( 22/ 7 ) × ( - 7 / 3 )

y = 25/ 3 + 22 / 3

y = ( 25 + 22 )/ 3

y = 47/ 3

Two solutions are

( 7 , 1 ) , ( -7 , 47 / 3 )

I hope this helps you.

Answer:

πx+3y=25

Step-by-step explanation:

y = (25-π×x)/3

y = 25/3-π×x/3

if x=7

y = 25/3- (22)/3

y = 25/3-22/3

y = (25-22)/3

y = 3/3

y = 1

hope this help you
