Which of the following is equal to the expression listed below?
27 + 18
a.
(9 × 3)(9 × 2)
b.
9 + (3 × 2)
c.
9(3 + 2)

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
