Answer:
0.375
1.4
3
1.66666666667
Step-by-step explanation:
Divide the numerator (top number) by the denominator (bottom).
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 first one is 2x^2+2x-2
the second one is 2x^2-2x-2
the third one is 6h+6k
