Question

Trevor solved the system of equations below. What mistake did he make in his work? 2x + y = 5 x − 2y = 10 y = 5 − 2x x − 2(5 − 2x) = 10 x − 10 + 4x = 10 5x − 10 = 10 5x = 0 x = 0 2(0) + y = 5 y = 5 A) He should have substituted 5 + 2x B) He combined like terms incorrectly, it should have been 4x instead of 5x C) He subtracted 10 from the right side instead of adding 10 to the right side D) He made no mistake

Answer 6

Trevor solved the system of equations below. What mistake did he make in his work?
2x + y = 5
x − 2y = 10
y = 5 − 2x x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10
5x = 0
x = 0
2(0) + y = 5
y = 5
A) He should have substituted 5 + 2x
B) He combined like terms incorrectly, it should have been 4x instead of 5x
C) He subtracted 10 from the right side instead of adding 10 to the right side
D) He made no mistake

Answer 7

Yes now it is very clear and I found out the mistake... where do you think he made a mistake?

Answer 8

B

Answer 9

Nop now you made a mistake

Answer 10

Is it A?

Answer 11

ITS JESUS

Answer 12

ITS THE JESUS BUS

Answer 13

JESUS CARES ABOUT MATH

Answer 14

Hello you still there @mecharv

Answer 15

Yes it is not A either... see
5x-10=10
then, 5x=20 right??

Answer 16

So it is C right?

Answer 17

Perfect :) But make sure you get better hold of the concept :)

Answer 18

Yes, but do you see why?

Answer 19

Of course.

Answer 20

It's a good practice to explain now why C is correct and why A, B and C are not. This way you'll get a good understanding of the concepts involved. Try it.
