Question

Solve the system of equations using the substitution method. Enter the answer as an ordered pair.

3x - y = 3
y = 2x + 2

Answer 1

-1, 0

Answer 2

3x - (2x +2) = 3, now you continue...

Answer 3

y= -3x +y

Answer 4

3x-(2x-2)=3
3x-2x-2=3
x-2=3
x=5
i think...my brain is kinda fryed from all the math lol

Answer 5

substitution= get the equation in the term of one variable, and then plug that into the second equation.
ex. a+b=1, and a*b=0
Get the 1st equation in terms of a (or b)
a=1-b
plug that in wherever u see a in the second equation.
(1-b)*b=1

Answer 6

For this one, I'd get the 1st equation in terms of y
3x-y=3
-y=3-3x
y=-3+3x

Answer 7

x = 5 y = 12

Answer 8

as an ordered pair that would (5,12)

Answer 9

Now plug that in wherever u see y in the second equation.
-3+3x=2x+2
x=5

Answer 10

Now that u know x=5, go back to one of the original equations, plug in a 5 wherever u see x, and solve for y

Answer 11

y=2(5)+2
y=10+2
y=12

Answer 12

many answers r suitable for this questions

Answer 13

So x=5, y=12.
