Question

what is 4x+3y= -5 and -3x+4y=12 in elimination?

Answer 1

Answer:

Step-by-step explanation:

4x+3y=-5   ...(1)

-3x+4y=12   ....(2)

By 3(1)+4(2) gives

12 x+9y-12x+16y=-15+48

25y=33

y=33/25=1.32

from (1)

4x+3(33/25)=-5

4x=-5-99/25=(-125-99)/25=-224/25

x=-224/100=-2.24

Answer 2

4x+3y=-5 answer 4x+34+5=0 -3x+4y=12 answer 3x-4y+12=0
