Question

Last onnee :DD

x + 3y = -5
2x - y = 18
Solve the systems using substitution

Answer 1

start with
x=-5-3y

and plug that into the 2nd equation.

Answer 2

wanna try ?

Answer 3

i would start with x=3(-18+2x)=-5

Answer 4

that works too :)

Answer 5

??? huh ill try but i do not understand :( and which one do i start with

Answer 6

you can try doing it both ways for practice.

Answer 7

you'll get the same answer either way

Answer 8

using this method you need to find a way to plug in one of the equations into the other one you get that part right

Answer 9

x=3(-18+2x)=-5
x= -54+6x=-5
+54 +54
x=6x-5
???? i dont think im doing this right haha
