Variables on Both Sides (22-23)

Solve:
7x = 3x + 24

• 6
• 10
• 14
• 4

Jacob solved the following equation using the steps shown.

Step 1 5x + 9 = 2x - 3

Step 2 3x + 9 = -3

Step 3 3x = -12

Step 4 x = -4

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation

What is the first step you should take to solve this problem?

-3(x - 2) = -8 +9b

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2

• add 2 to both sides

What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

• add 1 to both sides

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.

Solve for x:
4(1-x) + 3x = -2(x+1)

• x = -6
• x = 6
• x = 3

Solve:
5y + 34 = -2(-7y+1)

• y = -4
• y = 9
• y = 4
• y = 36/19

4k + 24 = 6k -10

• k = 17

• k =-17

• k= 5

• k = 1/5

13y - 18 = -5y + 36

• y = 3

• y = -3

• y= 9

• y = -9

8d - 25 = 3d

• d = 5

• d= -5

• d = 1/5

• d = -1/5
