Solving Linear Equations (Two-Step Equations)

Solve for x.

3x - 5 = -26

• x=-21

• x=21

• x=-7

• x=61

Solve for x.

-4x + 1 = 21

• x=120

• x=5

• x=30

• x=-5

Solve for k

3k + 5 = 23

• k = 4

• k = 5

• k = 6

• k = 7

 $Solve\ for\ y$  

 $3y\ -\ 6\ =\ 30\$  

•  $y\ =\ 8$  

•  $y\ =\ 12$  

•  $y\ =\ 16$  

•  $y\ =\ 4$

 $-\ x\ -\ 9\ =\ -11$   $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ Solve\ for\ x$  

•  $x\ =\ -2$  

•  $x\ =\ 20$  

•  $x\ =\ -20$  

•  $x\ =\ 2$  

The second step in solving the equation 2x - 3 = -15 is to . . .

• divide by 2 on both sides of the equation

• multiply by 2 on both sides of the equation

• subtract 3 on both sides of the equation

• add 3 on both sides of the equation
