Zuleika was solving 2(x - 3) - 9 = 3x - 9. zuleika's first step resulted in 2(x - 3) = 3x
because she used the multiplication/addition property of equality. the second
step resulted in 2x - 16 = 3x because she collected like terms used the distributive
properly. in the next two steps, zuleika used the addition/multiplication property
twice to get -x = 6.she then found the solution, x = -6, by using the
addition/multiplication property of equality.
