Question

Which equation has no solution?
A. 4(x + 3) + 2x = 6(x + 2)

B.5 + 2(3 + 2x) = x + 3(x + 1)

C. 5(x + 3) + x = 4(x + 3) + 3

D.4 + 6(2 + x) = 2(3x + 8)

Answer 1

Do you know how to rearrange equations?

Answer 2

Let me give you an example:
7(x+4)+2=3(x+1)
7x+7*4+2=3x+3*1
7x+28+3=3x+3
7x+31=3x+3
7x=3x+3-31
7x=3x-28
4x=-28
x=-7

Answer 3

Do you understand what I did at each step?

Answer 4

yea i kinda understand

Answer 5

Hmm, where did you not understand? because you need to fully understand if you want to do it yourself!

Answer 6

im kinda getting messed up at the end oh wait i get it just divide at the end

Answer 7

Good! Now you need to do what I just did for each of your equations

Answer 8

ok awesome thank you you helped me understand it more!

Answer 9

y r u solving for x ?

Answer 10

If you end up with a number equal to a DIFFERENT number then it means that you can't solve the equation

Answer 11

ok thanks :)

Answer 12

For example, if you start with 4x+3=2(x+4). Then, when i attempt to rearrange:
4x+3=2(2x+4)
4x+3=4x+8
3=8
Since I have a number equal to a different number, it means that you can't solve the equation

Answer 13

just add each side...if they dont equal, there is no solution...u dont have to solve for x

Answer 14

ok

Answer 15

it was B

Answer 16

yup :)
