Answer:
7
Step-by-step explanation:
x-3=4
x=4+3
x=7
Just plug in 1 and 2 for x and it will give you y then write it as (x,y) cordinates
Multiply 18hours by 60 seconds, the answer is 2880 seconds.
Answer:
x= -2, y = -3
Step-by-step explanation:
1. substitute x = 4+2y in the first equation: 
simplify it : 
2. isolate y in 8 + 5y = -7 --> 5y = -7 - 8 -->
3. solve for y: 5y = -15 --> y = -15/5 --> y= -3
4. solve for x: x = 4 + 2y
x = 4 + 2(-3)
x = 4 + (-6)
x = -2
