So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;
2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5
Hope this helps you. Any questions please ask.
The answer is 1.6
How I figured it out:
I divided 8 by 5, which gave me 1.6
To make sure this was right, I multiplied 1.6 by 5, which gave me an answer of 8 or other known as 8 inches.
In conclusion, the number of inces per hour is 1.6
27.5 and 22.5 are the two numbers
