Unit 2 Review

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a 

2h = w-3p
(solve for p) 

• p = -(2h - w) / 3
• p = (2h - w) / 3
• p = -6hw
• p = -6h - 3w

 $5x+4=5x+4$  

• one solution

• no solution

• infinite solutions

 $-2\left(x+1\right)=x-3x-2$  

• one solution

• no solution

• infinite solutions

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Figure out what n equals in this equation:
6n + 4 = -26

• n=-6
• n= -5
• n= 8
• n= -4

 $96=6\left(k+8\right)$  

•  $12$  

•  $8$  

•  $-4$  

•  $9$  

4 = 2(x + 3)

• 1/2
• 7/2
• -1
• 5
