Question

-3x-4y-2=0 and 4x-3y+2=0solve this by elimination and substitution method​

Answer 1

Answer:

elimination method

-3x-2y=2

4x-3y=-2

-12x-8y=8

-12x+9y=6

-17y=2

-y=2/17

y=-2/17

-3x-2y=2

-3x-2(-2/17)=2

-3x+4/17=2

-3x=2-4/17

-3x=34-4/17

-3x=30/17

-x=(30/17)/3

-x=30/17*1/3

-x=10/17

x=-10/17
