Solving Multiple Step Equations with Parentheses and Distribution

What is the first step in solving this equation? 2a - 4(a - 5) = 10 Choose your answer and then show your work to find the solution.

• Add 4 to both sides

• Add the 2a and a

• Distribute 4 into the parentheses. This means you will do 4 times a and 4 times -5 and end up with 2a + 4a -20 = 10

• Distribute -4 into the parentheses. This will mean you will do (-4 time a) and (-4 times -5) and end up with 2a -4a + 20 = 10
