5 - x = 7 - 2x could be the result of using the comparison method to solve the system shown: x + y = 5 , 2x + y = 7 .
Equation 1 : x + y = 5 , so y = 5 - x
Equation 2 : 2x + y = 7 , so y = 7 - 2x
And 5 - x = 7 - 2x
Confirmed by jeifunk [11/26/2014 2:30:01 AM]
For the following system, use the second equation to make a substitution for x in the first equation : x + 5y - 10 = 0 , x = 2y - 8 , we get 7y - 18 = 0 , so the solutions is x = -20/7 , y = 18/7 .
x + 5y - 10 = 0
2y - 8 + 5y - 10 = 0
7y - 18 = 0
y = 18/7
x = 2*18/7 - 8
x = 36/7 - 56/7
x = - 20/7
