12x - 8x + 9
4x + 9
Solve for x
-3(4x + 6) = -18
x = 0
Which of the following represents infinite solutions
A) 2x + 5 = 13
B) 45 = 45
C) 17 = 20
D) x = -4
B
Simplify
4(3x + 6)
12x + 24

Mr.Scarpaci solved this problem incorrectly. Describe the error he made AND solve it correctly.
3(2 - 3x) + 5x = 34
6 + 9x + 5x = 34
6 + 14x = 34
14x = 28
x = 2
When Mr.Scarpaci multiplied 3 and -3x he got + 9x instead of - 9x.
x = -7
Simplify
-10y + 2x + 7y - 5x
-3y - 3x
Solve for x
2(3x − 4) − 8 = 5 + 3x
x = 7

Tristyn stated that there is no solution to the equation:
8 + 4x = −2(−9x − 4) + 6x
Do you agree or disagree? Explain your reasoning.
I disagree with Tristyn because when I solved the equation I got x = 0. 0 is a solution therefore there is only 1 solution.
Simplify
-2(3x - 5) - 8 + 6x - 3
-1 or 0x - 1
Solve for x
15x − 35 = −3(2 − 5x)
-35 = -6

Jonah has two job offers at a gym. One has a base monthly salary of $2530 and an additional $20 commission per new client he gets to join the gym. The other offer does not have a base salary but he gets $250 for every new client who joins the gym.
How many clients would Jonah need to get to join the gym each month to make the second offer better than the first?
Jonah would need 12 clients to join each month to make the second offer better than the first.
(11 clients for it to be equal)
