9/14 - 9/18 Weekly Recap + (test)

What is the first step in solving this equation:

5x + 7 = 12

• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

What is the first step to complete when solving this equation?

10 - 3y = 4

• Add 10 to both sides

• Subtract 10 from both sides

• Add 3 to both sides

• Divide by -3 on both sides

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

Solve:
-4x = 24

• 20
• -20
• 6
• -6

Solve:
3(x - 2) = 18

• 6.7
• 4
• 8
• -4

  $13=\frac{r}{9}+8$  

• 45

• 5

• 17

• 15

Solve for y:
8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

IR = V
(solve for R) 

• R = IV
• R = ^I/_V
• R = ^V/_I
• R = V - I

Solve:
y = mx + b , for b

• y - mx = b
• y + mx = b
• ^y/_mx = b
• y + mx = -b

• The wrong inverse operation is used.

• 17 + 5 is not 22.

• 5 isn't being added to both sides of the equation.

• The unknown value, x, should not be 22.
