Question 5546
X/2 + 2y =9 --> multiply it by 4, because i do not want to work with fractions.
2x-y = 18


2x + 8y = 36
2x -  y = 18


Subtract the 2 equations, to give 9y = 18
so y = 18/9
y = 2


Hence, 2x-2 = 18
2x = 20
so x = 20/2
x = 10


check in other equation: 10/2 + 2(2)
5 + 4
--> 9 which is the correct answer for that equation.


so my answers are correct.
