What do the following two equations represent? -2x-4y=-3 6x+12y=9

it is a simultaneous equation and x=1.5 and y=0

Step-by-step explanation:

-2x-4y=-3

6x+12y=9

make x the subject of formula in equation 2

6x+12y=9

6x=3-12y

divide both sides by 6

6x/6=3-12y/6

x=3-12y/6

substitute x=3-12y/6 into equation 1

-2(3-12y/6)-4y=-3

-18+24y/6-4y=-3

cross multiply

-18+24y-4y=-18

collect like terms

24y-4y=-18+18

20y=0

divide both sides by 20

20y/20=0/20

y=0

substitute y=0 into equation 2

6x+12(0)=9

6x+0=9

collect like terms

6x=9-0

6x=9

divide both sides by 6

6x/6=9/6

x=3/2=1.5

so x=1.5, y=0
