It can be solved by factoring or taking the root of both sides.
x= 2 radical 3. and -2 radical 3
Write an equation
10 + 3x = 15 +2x
-2x -2x
-----------------------
10 + x (1x) = 15
-10 -10
----------------------
x = 5
cost= 25 (10 + 15)
Undefined is the answer because there is no value for x
Here is your answer!
B) The determinent is 0
1/4(6 + 2c) > 3
0.25 (6+ 2c) > 3
1.5 + 0.5c > 3
0.5c > 1.5
c > 3
Or multiply both sides by 4 to get rid of the 1/4,
6 + 2c > 12
2c > 6
c >3
