Question

x+2y=10 &2x-4y=-4 (pair of equation in two variable)​

Answer 1

Answer:

x=4, y=3

Step-by-step explanation:

Use elimination method, multiply 1st equation by 2 to make coefficient of y equal.

2x+4y=20

2x-4y=-4

Now, add the 2 equations to eliminate y,

4x=16

x=4

Put x=4 in equation 1,

4+2y=10

y=3
