Answer:
Solutions are (6,3) and (-2,3).
Step-by-step explanation:
From the first equation given we can write:
substituting for 
in the second equation given we get
∴ y=3
Putting y=3 in the first equation we get
x-2 = ±4
Hence x=6 or x=-2.

Step-by-step explanation:
It costs 79 dollars a month = 79x
It costs 0.15 dollars for every text message over 1000 = 0.15y
The equation is:
79x + 0.15y = z
X = months
Y = Each text message over 1000
Z = the total amount spent
Let's plug in our values
79(1) + 0.15(1100) = z
79 * 1 = 79
0.15 * 1100 = 165
79 + 165 = z
79 + 165 = 244
z = 244
