Solve 5x-3y =1,
3x-y=5.

Step-by-step explanation:

5x-3y=1

5x=1+3y

x=1+3y

5

and

3x-y=5

3x=5+y

x=5+y

3

now, 1+3y= 5+y

5 3

3(1+3y)= 5(5+y)

3+9y= 25+5y

9y-5y= 25-3

4y=22

y=22

4

y= 11

Step-by-step explanation:

5x - 3y = 1

3x- y = 5                    Multiply this equation by -3:

-9x + 3y = -15            Now add this equation to the first equation:

-4x = -14

x = -14/-4 = 3.5.

Now substitute for x in equation 1:

5(3.5) - 3y = 1

-3y = 1 - 17.5

-3y = -16.5

y = 5.5.

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
