Question

draw the graph of the linear eq 2x+y=7 find the value of
I)x when the value of y is 3
ii)y when the value of x is 4
also write one more solution of the given eq​

Answer 1

Answer:

Step-by-step explanation: if y=3 then X

2x+y=7

2x+3=7

2x=7-3

2x=4

x=4/2

x=2

(i) hence x=2

if x=4 then y

2x+y=7

2x4+y=7

8+y=7

y=7-8

y=-1

(ii) hence y=-1

if x=o then y

2x+y=7

2xo+y=7

o+y=7

y=7

(iii)hence y=7
