2. What is the solution to the system of equations y = 3x + 3 and y = 2x + 1?
A) no solution
B) (-1, 3)
C) infinite number of solutions
D) (-2, -3)

Answer 1

@Daniel56k

Answer 2

plug in y=3x+3 into y=2x+1

Answer 3

Why not actually solve this system yourself and then check your answers against the given possible answers?

Both your equations begin with 'y'. Set one equal to the other, which in effect eliminates y. Then, find x. Next, calculate y.

Answer 4

then it will look like this
3x+3=2x+1

Answer 5

after solving that plug in your answer into either y=3x+3 or y=2x+1

Answer 6

@Daniel56k

y = 3x + 3
y = 2x + 1

x = -2 and y = -3

Answer 7

that is correct

Answer 8

follow the step i gave you

Answer 9

finish it up by finding x and plug x into equation 1 or 2 to get y

Answer 10

okay subtract both side by -2x-3

Answer 11

and that is how you find x
then plug x into y=2x+1

Answer 12

okay 3x-2x=-3+1
x=-2
y=2(-2)+1
y=-3

Answer 13

Is your final answer a point? If so, please write it in the form (x, y).

Answer 14

yes
