Question

LINEAR EQUATION IN TWO VARIABLES.



FIND TWO SOLUTIONS FOR EACH OF THE FOLLOWING EQUATIONS:-


3y+4=0

HINT:-

[ YOU HAVE TO PUT VALUE TO OF y . SO THAT 3y+4 IS EQUAL TO 0. ]
​

Answer 1

) 4x+3y=12

for y=4

4x+12=12 x=0

for y=0

4x+0=12 x=3

(0,4) & (3,0) are 2 solution

2) 2x+5y=0

for y=−2

2x−10=0 x=5

for y=−4

2x−20=0 x=10

(5,−2) and (10,−4) are 2 solutions

3) 3y+4=0

y=

3

−4

is only solution
