Question

describe how two different ways to use elimination to solve the system
 {3x-4y=-1 
5x+4y=-5

anonymous · Answer

either u can eliminate x from both equations or y from both equations

i think what she meant is what should you multiply...

anonymous · Answer

no i think @mayank_mak is right

anonymous · Answer

@chikitagee so u can solve further.

anonymous · Answer

take the LCM of x coefficient in both equations.
In this problem it is 15. so multiply the (3x-4y = -1) with 5 to make 15
and multiply (5x+4y=-5) by 3 to make the coefficient of x 15
 then subtract both equations to get value of y
