Step-by-step explanation:
2x-3y=6
2x-3y-6=6-6
2x-3y-6=0
4x-6y=12
4x-6y-12=0
2×-3y-6y=0
Answer:
4478 m
Step-by-step explanation:
Altitude 1= A1= Mt Whitney is at 4392 m above sea level.
Altitude 2= A2= Bombay Beach is -86
Difference in Altitude= A3=?
A3 = A1 - A2 (because A1 is mentioned first and is the greater altitude)
A3 = 4392 - (-86)
= 4392 + 86
A3 = 4478 m
X=2+5y
x-y=30
basically, all you're doing here is solving a system of equations. use the second equation to find out what x or y means. i'm going to solve it for x.
this is the new equation : x=30+y
now i plug this equation into the first one.
30+y=2+5y
30=2+5y-y
30=2+4y
28=4y
y=7
now that you know what y is, take that second equation we did in the beginning and plug in y.
x-7=30
solve for x
x=37
the two integers are 37 and 7.
