Solving Equations using the calculator

Solve the equation:
-5x = 25

• x = 20
• x = -20
• x = -5
• x = 5

x - 8 = -5 

• 13
• -13
• 3
• -3

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Solve for k:
3k + 5 = 23

• k = 4
• k = 5
• k = 6
• k = 7

Solve: 3(x-4) = -3

• 3
• -3
• 5
• -5

Solve the equation
-8x - 8 + 3(x - 2) = -3x + 2

• x = -8
• x = 8
• x = 2
• x = -2

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.

A toy company spends $1500 per day for factory expenses plus $8 to make each teddy bear.  They sell the teddy bears for $12 a piece.  Which equation could be used to find the number of bears t the company has to sell in one day to equal its daily cost?

• 1500 + 8t = 12
• 12 + 8t = 1500
• 1500 + 8t = 12t
• 8t = 12t + 1500

Solve for x: 
4x + 1 = 7x - 5

• -1
• 2
• 6/11
• 8
