Question

2x+y=10
-5x-y=-19
Solve using system of equations

Answer 1

this is a system of equations lets use substitution :)
\[-5x-(-2x+10)=-19 \]
i subtracted 2x from the first equation to get y equals.... and plugged it into the 2nd equation can you solve from there?

Answer 2

Wait woah aren't we supposed to solve for x first?

Answer 3

this is the way to do it :D solve the equation

Answer 4

I got x=3

Answer 5

Answer 6

And i got y=4

Answer 7

lets do:
multiply both equations by 2 we get:
4x+2y=20 and
-10x-2y=-38
now when we add them we got:
-6x=-18
x=3 now put it in first equation we get:
y=4

Answer 8

Yup you are right!
