Answer 7
Explanation
you need to divide 63 by 9 to get 7
Well if you use graph paper you can graph the points you already have and then you can find the slope of the line easiest that way, the next point would be. (-1,8)
Step-by-step explanation:
4x+5y=4 (equation 1)
2x-y=9 (equation2)
solving equation 1 and 2 and multiplying equation 2 by 2
4x+5y=4
4x-2y=18
- + -
________
7y= -14
y= -2
putting the value of y in equation 2
2x-y=9
2x+2=9
2x=7
x=3.5
