Question

solve by elimination method. 3x + 4y =0, 2x-2y =2 ​

Answer 1

Answer:

3x+4y=0. x1

2x-2y=2. x 2

4x-4y=4

3x+4y=0

7x=4

x=7/4

3x7/4+4y=0

21/4+4y=0

5.25+4y=0

4y=0-5.25

y=-5.25/4

y=1.3125

hope helps u

Answer 2

Answer:

Hope this helps

Step-by-step explanation:

3x+4y=0

2x-2y=2

multiplying first equation by 1 and second by 2 we get

3x+4y=0

4x-4y=4

after adding

7x=4

x=4/7

now

3(4/7)+4y=0

12/7+4y=0

4y=-12/7

y=12/28

y=3/7

ans :- x=4/7 and y=3/7
