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

8x = 72
x = ?
3. This can't be answered because it's only one equation, but there are two variables.
