solve equation then check for extraneous solution please someone explain this to me.
6/64x/=8+4
then one that is solve the inequality
s/x+3/4<2
I don't understand these problems and then it says to graph

1. 664x = 4+8 = 12.
Divide both sides by 6 to isolate bracket:
64x = 2
64x = +2
4x = +2  6
4x = 26 = 4
X = 1.
4x = 26 = 8
X = 2.
Solution set: X = 1, and X = 2.
2. 5x+34 < 2.
20x+3 < 2
x+3 < 2/20
x+3 < 1/10
x+3 < 1/10
X < 1/10  30/10
X < 29/10.
x3 < 1/10
x < 1/10 + 30/10
x < 31/10
X > 31/10.
Solution set: < 29/10, and X > 31/10.
