Consider this system of equations:
2/3x+ 3/5y=12 (equation A)
5/2y−3x=6(equation B)
The expression that gives the value of x is ↓.
The solution for the system of equations is ↓.
↓5a/3+ 2b/5 3a/5− 5b/25a/2+ 3b/55a/3− 2b/53a/2+ b/5 ↓(1118/47, 396/47) (33/13, 50/13)(99/13, 150/13)(8,12)
(2/3)x + (3/5)y = 12
-3x + (5/2)y = 6
Mutiply the first equation through by the common denominator of 3 and 5 = 15
Multiply the second equation through by 2
So we have
10x + 9y = 180 multipy through by 6 = 60x + 54y = 1080 (1)
-6x + 5y = 12 multiply through by 10 = -60x + 50y = 120 (2)
Add (1) and (2)
104y = 1200 divide by 104
y = 1200/104 = 600/52 = 150 / 13
Obviously, only one answer has a "y" answer that = 150/13.....so that must be the correct one
