Asked by Hazel

solve each equation:
1) x + 2x - 6 + 6
MY ANSWER:
x-x + 2x-x +12
_______________
x=12

2) 3x + 9 + 5x =81
MY ANSWER:
3x-3x + 9x + 5x-3x = 81
9 + 2x = 81
9-9 + 2x = 81-9
2x = 72
2x/2 = 72/2
x=36

3) x - 2 = -4 + 7w
I need help with this one
Answered by Ms. Sue
1. You don't show an equation, so we can't know what x equals.

2. No.
3x + 9 + 5x =81
8x = 72
x = ?

3. We can't do this one because it has only one equation, but two variables.
Answered by Hazel
1) x + 2x - 6 = 6
2)x=9
3) That is how the equation is showed so, I don't know what else to do
Answered by Hazel
oh wait #3 is supposed to be:
w - 2 = -4 + 7w

sorry, my bad
Answered by Ms. Sue
1) x + 2x - 6 = 6
3x = 12
x = ?

2)x=9 yes

3)
w - 2 = -4 + 7w

2 = 6w
? = w

In number 3, w does NOT equal 3.
