Question

Solve the following system and show all of your work.
x − 2y = 14
x + 3y = 9

Answer 1

subtract the first eqn from the second eqn.
Vat do u get when u do so?

Answer 2

x=12
y=-1

Answer 3

3y=9-x
y=9-x/3
then sub in eq 1
x-2*(9-x/3)=14
then 3x-18+2x=42
x=60/5=12

Answer 4

y=-1
x=12
subtractin 1from2
we get
-5y=5
therefore y=1
puttin y=-1 in 1
x =14-2
x = 12
