X-7y=53 -4x-5y=19 solve for x and y

y = -7; x = 4

Step-by-step explanation:

x - 7y = 53

x = 7y + 53

-4x - 5y = 19

-4(7y + 53) - 5y = 19

-28y - 212 - 5y = 19

-33y = 231

-11y = 77

y = -7

x - 7(-7) = 53

x + 49 = 53

x = 4

step-by-step explanation:

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
