Question 954219
3. x = z/2
****************************************
the second equation becomes
z/2 + y = z
y = z/2
***************************************
the first equation becomes
z/2 + z/2 + z = 90
2z = 90
z = 45
x = 22.5 and y = 22.5
***************************************
equation 1
22.5 + 22.5 + 45 = 90
90 = 90
************************************
equation 2
22.5 + 22.5 = 45
45 = 45
*************************************
equation 3
22.5 = 45/2
22.5 = 22.5
