Question

8. Solve the following system of equations graphically :
(i) 3x-2y = 12
5x-2y=4​

Answer 1

Answer:

by elimination method

Step-by-step explanation:

3x-2y=12×1

5x-2y=4×1(To eliminate y)

now=changing the sine

3x-5x=12-4

-2x=8

x=-4

putting value of x in 1st

3×-4-2y=12

-12-2y=12

-2y=12+12

y=-12

so ×=-4andy=-12

Elimination is best method to solying any eqn
