SOLUTION: I'm not really sure if this is linear equations or not..
solve the system of equations by graphing and then classify the system
2x+y=4
3x+4y=-14
Question 251540: I'm not really sure if this is linear equations or not..
solve the system of equations by graphing and then classify the system
2x+y=4
3x+4y=-14 Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! Yes they are both linear equations which produce lines
There are no more than two variables and no powers (exponents) greater than one.
to graph
set x=0 and solve for y
set y=0 and solve for x
do that for both original equations
solve by elimination
multiply the first equation by 4 and subtract the new equation from the second equation
solve by substitution
set 2x+y=4
as
y=4-2x
substitute 4-2x for y in the second equation
