Let me know if you have questions!
What you're going to do is plug in y=2x+5 into the 3y ( getting rid of the y to solve for x only) so that gives you...... 6x-3(2x+5)=6. Next, you're going to multiply -3 to 2x and 5. Now it gives you..... 6x-6x-15=6. The x's cancel out leaving the equation with -15=6 making it an Inconsistent system also known as a No Solution system.
If you need area of the trapezoids:
Area of parallelogram = 10×7 = 70 sq. units
Area of each trapezoid = 1/2 × area of parallelogram = 1/2 × 70 = 35 sq. units
6.51 - 9.32h = 1.02
9.32h = 6.51 - 1.02 = 5.49
h = 5.49/9.32 = 0.589
