Question

Solve the pair of linear equations graphically: x - 2y =0 and 3x + 4y = 20​

Answer 1

Answer:

x-2y=0

x=2y

if y is equal to one then

x=2

if y is equal to three then

x=6

if y=1,x=2

if y=3,x=6

3x+4y=20

3x=20-4y

x=20-4y÷3

if y is equal to 1

x is equal to 5.9

if y is equal to 2

x is equal to 4
