Best ResponseYou've already chosen the best response.0take the second equation an make x the subject of the formula x=3/y Afterwards replace the x value with 3/y to find y. After finding y raka u then substitute y value on the secon equation to find x simple:)

Best ResponseYou've already chosen the best response.0x+y=3 tomake x the subject we have x=3y Now since 3x/8y=24 =3(3/y/8y)=24 =9/y/8y=24 simplying this further we get 9/y*8y=24 =8y^2/9=24 and then multiply by 9 both sides tog 8y^2=216 the divide by 8 both sides to get y^2=27 then take the sqrt both sides to get your y as=5.196 =5.2 Afterward u take this y value put it in the second equation to find ur x value x+y=3 x+5.2=3 x=2.2

Best ResponseYou've already chosen the best response.0rika a u still there.sry I made a huge blander i thought that it was + was division sign again. y=3x from second equation now take that y and replace it with the y on the first equation =3x+3x=24 =2x=21 x=21/2 x=10.5 for your y x+y=3 10.5+y=3 y=7.5

Best ResponseYou've already chosen the best response.0there are many ways of killing a cat substitute my x and y valu on the second equation u`ll still get 3 10+(7.5)=3
