PLEASE ANSWER

A. (-4, 5)
B. (8, 1)
C. (3, -2)
D. No solution
E. Infinite number of solutions

C. (3, -2)

Step-by-step explanation:

x + y = 1 ➡ x = 1 - y we can use this information in the first equation to find the value of y

3x - 5y = 19 replace x with 1 - y

3 ×(1-y) - 5y = 19 ➡ 3 - 3y - 5y = 19 add like terms

-8y = 16

y = -2 if y is 2 then x is

x + y = 1 ➡ x +(-2) = 1 and x = 3

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
