Answer 1

Hope it will help you...

Answer 2

Answer:

given equations are

3x+4y=10; →→→(1)

2x-2y=2 →→→→(2)

Step-by-step explanation:

on multiplying (2) by 2 we get

4x-4y=4

now adding it to (1) we get

3x-4y=10

4x-4y=4

7x=14

x=2

putting x=2 in (1)

6-4y=10

y=-1

this was elimination method
