3x - 5 = - 26

• x = - 21

• x = 21

• x= - 7

• x= 61

Solve: 3(x - 4) = -3

• 3

• - 3

• 5

• - 5

Solve for x: 
4x + 1 = 7x - 5

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k

Solve for y:( Make y the subject)

3x + y = 12

• y = 12 - 3x

• x = y + 4

• x = y + 12

• y = 3x -12

 $dx+e=f$ 
 Which expression represents the value of x in the equation:

•  $x=\frac{f+e}{d}$ 

•  $x=\frac{f-e}{d}$ 

•  $x=\frac{d}{e-f}$  

•  $x=\frac{d}{e+f}$
