Answer:
Step-by-step explanation:
2x+y=14+y
x=7
7+13y=35-y
14y=28
y=2
Answer:

Step-by-step explanation:
First, you need to divide everything by 6.
Then you put everything in a radical to get this:

Answer:
Step-by-step explanation: (Equation 2) = 12(-12+9y/4) - 10y = -8
-144+108y/4 - 10y = -8
-144 + 108y - 40y/4 = -8
-144 + 108y - 40y = -32
108y - 40y = -32+144
68y = 112
Y= 1.64
2-4x+9y=14
12x-10y= -8
2-14+9y = 4x
-12 + 9y = 4x ( equation 3)
(Put in equation 2)
