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
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.
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
oh wait #3 is supposed to be:
w - 2 = -4 + 7w
sorry, my bad
1) x + 2x - 6 = 6
3x = 12
x = ?
2)x=9 yes
3)
w - 2 = -4 + 7w
2 = 6w
? = w
1) x=4
3) w=3
