Question

Write 4 linear equations in two variables using x and y​

Answer 1

Answer:

if x = 0

22*0/7 + y = 9

0+y = 9

y = 9

if x = 1

22*1/7 + y = 9

y = 9-22/7

y = (63 - 22)/22

y = 41/22

if x = 2

22*2/7 + y = 9

44/7 + y = 9

y = 9-44/7

y = (63 - 44)/22

y = 19/22

if x = 7

22*7/7 + y = 9

22 + y = 9

y = 9-22

y = -13

Answer 2

Answer:

1. An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.
