Solve using subsitution
2x + 3y = 10
y = -x + 3

2x + 3y = 10

y = -x + 3 (plug -x+3 for y in the first equation because -x+3=y)

2x+3(-x+3)=10

2x+(-3x)+9=10

-x=1

x=-1

To find y, plug in -1 for x into any of the equations.  I will pick the second equation because it is easier.

y = -(-1) + 3

y=4

x=-1, y=4, intersection point: (-1,4)

step-by-step explanation:

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
