Question

Solse by Simultaneous equation graphically
3x -4y=-7 ; 5x -2y=0​

Answer 1

Answer:

x = 1 ; y = 5/2

Step-by-step explanation:

multiply the 2nd eq. with 2

10x-4y=0

now subtract first eq and the new eq

3x - 4y = -7

(-) 10x - 4y = 0

- +

we get,

-7x = -7

therefore, x = 1

substitute x = 1 in any of the equation and you'll get y = 5/2
