You can put this solution on YOUR website! 1)1. Solve the equation 3(2x-1) + x = 5x+3.
 . 0
b. 3
c. 3/2
d. no solution
3(2x-1)+x=5x+3
6x-3+x=5x+3
7x-3=5x+3
-5x+7x+3=-5x+5x+3
2x+3=3
2x+3-3=3-3
2x=0
2x/2=0/2
x=0 (a)

3)3. Solve by factoring:  .
a. 5, 14
b. -7, 2
c. 2, 7
 . 7, -2
 Two numbers that multiply to get -14, but add to get -5 are -7 and 2. -7*2=-14 and -7+2=-5
 and 
 and 
:
4)4. Solve the inequality 3x + 5< with - under < 7 . Write the solution using interval notation.
a. (- infinity; , 4]
b. [4, infinity )
 . (-infinity, 2/3]
d. [2/3, infinity )
(-infinity,2/3]
Happy Calculating!!!
