Question

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

Answer 1

Answer:

If y is equal to one then,

x = 2

If y is equal to three then,

x = 6

_________________________

y = 1 , x = 2

y = 3 , x = 6

__________________________

3x + 4y = 20

3x = 20 - 4y

x = 20 - 4y ÷ 3

Y is equal to 1

x is equal to 5.9
