Answer:
9 and 6
Step-by-step explanation:
Write down the system.
The two numbers are x and y.
We are therefore given:
x+y=15
x-y=3
I will solve this for elimination since it is already setup for it.
I will add the columns since both equations are in the same form.
2x+0y=18
2x =18
Divide both sides by 2:
x =18/2
Simplify:
x =9
So if x+y=15 and x=9, then y=6.
The two numbers are 9 and 6.
Test:
9+6=15
9-6=3
Answer:
289 messages
equation: 
graph: attached below
Step-by-step explanation:
We can write this in slope-intercept form, or 
. Since x is defined as the #of text messages, and 0.05 is the cost of a text message, 0.05 will be m. 45.5 is the base price, or the y-intercept, so it will be b.
Plugging in these numbers, we get 
now we make y = 60, since that is the total amount they have
So, they can send 290 messages for 60, but they need the bill under 60, so 1 text message less will be 289, and that's enough.
