Question

please solve this question
7x - 21 = 0 for 2 variable graph
please solve ​

Answer 1

Answer:

i can solve but i am not having graph so plot the points by yourself annd draw the line

Step-by-step explanation:

7x-21=0

7x=21

x=21/7

x=3

now we know the value of x and we can take any suitable number as y but remember if u take big numbers than it will become problem to draw line

let equation 1 be

x=3+0×y

now we can put value of y

y=0

x=3+0

x=3

.............

y=1

x=3+0×1

x=3+0

x=3

we can now make a table for it

for y=1 the value of x is 3 and for the value of y =0 value of x is same 3
