2x - 1 = 9 Solve for x.

2x - 1 = 9 Step 1: The first step is to get all the variables besides x to one side of the equal sign. Isolate the variable x to one side of the equal sign by adding 1 to both sides. We ADD one because it is the opposite of the sign in the equation. 2x = 9 + 1 ==> 2x = 10 Step 2: To solve for x, divide both sides by 2. We DIVIDE because it is the opposite of multiplication. (Remember that "2x" means 2 MULTIPLIED by x). 2x = 10 ==> x = 5
