Question

HELP!!!
I keep getting these wrong!!
-posting in comments-

Answer 1

[2.2 - 0.5x] = 3
2 equations when using absolute value
-(2.2-5x) = 3 and 2.2 - 0.5x = 3
-2.2-5x = 3 -0.5 x = 3-2.2
-5 x = 3 + 2.2 x = 0.8/-0.5
x = 5.2/-5 x = -1.6
x = -1.04

using the positive value x = -1.6
to check left hand side 2.2 - 0.5(-1.6) = 2.2 + 0.8 = 3.0 = R.H.S.

Answer 2

1-3x/7 = 2/3
using the positive value
multiply by the LCD 21 same as cross-multiply
3(1 - 3x) = 7*2
x = (14 - 3)/-9 =
and
x = 17/9

Answer 3

those were wrong too..... but thanks for trying @triciaal

Answer 4

1. x=89?
do you know what is the correct answer according to whoever is saying it is wrong?
