Question

write one linear equations in two variables with x=9 and y=4 as a solution​

Answer 1

Answer:

Given, πx+y=9

a) Put x=0, we have

π(0)+y=9⇒y=9

b) Put y=0, we have

πx+0=9⇒πx=9⇒x=π9 

c) Put x=1, we have

πx+y=9⇒π(1)+y=9⇒y=9−π

d) Put x=2, we have

πx+y=9⇒π(2)+y=9⇒y=9−2π

Hence, the four solutions of the given equations are: (0,9),(π9,0),(1,9−π),(2,9−2π).

Answer 2

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
