Translate this sentence into an equation.

A number c multiplied by six is equal to two more than d.

• 6c = d + 2

• 2c = d + 6

• c = d + 2

• c = 6(d + 2)

What is the first step to solve for k?

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.

In the equation

x + 7 = 12

7 is being added to the variable, x. What is the first step to isolate the variable and solve the equation?

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.

  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.

Solve the equation:
