What does it mean to 'solve' an equation?

• To eliminate all variables from the equation

• To find the value that makes the equation true

• To rewrite the equation in a different form

• To simplify the equation

In Example 1, what is the first step to solve the equation 3(X + 4) = -2(X - 5)?

• Combine like terms

• Use the distributive property

• Add 2 to both sides

• Subtract 4 from both sides

After distributing in Example 1, what is the resulting equation?

• 3x + 4 = -2x + 5

• 3x + 4 = -2x - 5

• 3x + 12 = -2x + 10

• 3x + 12 = -2x - 10
