Roman solved the equation 5 a + 2 b = 10 for a. His steps are shown below.
1. Subtract 2b: 5 a + 2 b minus 2 b = 10 minus 2 b. 5 a = 10 minus 2 b.
2. Multiply by 5: a = 50 minus 10 b.
Which statement about Roman’s work is true?
In step 1, he needed to add 2b to both sides of the equation.
In step 1, he needed to divide both sides of the equation by 2b.
In step 2, he needed to divide both sides of the equation by 5.
In step 2, he needed to subtract 5 from both sides of the equation.
