Maria wants to solve the following system using the elimination method: 4x + 9y = 59 x + y = 17 what number should the equation x + y = 17 be multiplied by to eliminate y? 4 9 −9 −4

60: 45 =12: 9 =4: 3 so the answer is 4: 3

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
