what is the graph of a no solution look like
it would have parallel lines and they don't intersect
200
solve:
-(3x-7)
-3x+7
200
what are the steps to solving elimination
step 1:eliminate one variable in order to solve
step 2:you will either add or subtract like terms in order to solve for a variable
step 3:use substitution to solve for other variable
200
what are the steps to solving substitution?
step 1:set both equations equal to each other
step 2:solve for variable, x
step 3:solve for variable, y if necessary
step 4:your solution will always be an ordered pair

what are the 2 ways of solving systems of equations
elimination and substitution
300
2(4x-3)=10
please solve
x=2
300
x-y=11
2x+y=19
x=10 y=1 (10,-1)
300
solve
y=7x-10 4=7x-10
y=-3 x=1
(1,-3)
300
where is the P.O.I (point of intersection)
it is where the lines intersect on the graph
400
solve the following with no calculator
-5(x-10)=2
x=9.65
400
what is the difference between elimination and substitution
the difference is that elimination is you take it out and substitution is you substitute something in
400
solve for x and y
y=9x-9 9=9x-9
y=9 x=2
(2,9)

what are the names of the solutions in this topic
infinite solutions
no solution
one solution
500
solve and then plug in your answer
3(5x+6)=48
x=2
3(5x2+6)=48
500
how many equations are you dealing with when using elimination
2 equations
500
y=2x-(-15) 5x=2x-(-15)
y=5x x=-5
(-5,-25)
500
if an equation is the same on both sides is it the following
)no solution
)infinite solution
)one solution
