For the equation - 0.4x + 10 = - 20 Monkey thinks the first step is to subtract 10 from both sides and then add 0.4 to both sides to isolate the variable. What error did she make?

• You are supposed to add 10 to both sides
• You are supposed to divide both sides by - 0.4
• You are supposed to divide both sides by 0.4
• No error, with a name like Monkey how could she be wrong
