Ryan, Jessica, and Mark each solved this system of equations. All of their answers are different. Find and explain the mistakes.

What is the correct answer?
y = 3x + 2
6x – 2y = 10

Ryan’s answer:
I solved by adding the equations. The solution is .

y = 3x + 2 → 3x + y = 2
6x – 2y = 10 → 3x – y = 5
6x = 7
x =

6x – 2y = 10 → 6 – 2y = 10

7 – 2y = 10
–2y = –3

y = -

Jesse’s answer:
I used matrices. The solution is .



Mark’s answer:
I graphed the equations. The lines are parallel and do not intersect, so there is no solution.

6x - 2y = 10
-2y = -6x + 10...reduce by dividing by -2
y = 3x - 5....slope = 3 and y int = -5

y = 3x + 2 ...slope = 3, y int = 2

These lines are parallel. Parallel lines will have the same slope, but different y int's. There is no solution to this because ur lines never intersect.

I need help on this
Mariana [72]

Isolate the w

w/3 = 5

Note the equal sign. What you do to one side, you do to the other.

Multiply 3 to both sides

w/3(3) = 5(3)

w = 5(3)

Multiply

w = 15

15 is your answer for w

hope this helps
