4 times a number increased by 5 is the same as 3 times the difference of a number and 2.  Which of the following equations would find the number?

• 4n + 5 = 3n - 2
• 4n + 5 = 3(n - 2)
• 4n+5 = 3(n + 2)
• 4n + 5 = 3 - 2n

What is the first step in solving this equation?
5(2x - 1) + 7 = 4x + 11

• Combine like terms
• Use the distributive property to get rid of the parenthesis
• Add 7 & 11
• Add 2x & 4x

Simplify the expression: 7v + 2 + 12 + 2v
