. An elevator starts at the 6th floor. It goes up 7 floors twice, and then it goes
Anettt [7]

Well let's see what floor each one lands on and figure out which one is higher.

Something to note:

down = subtracting

up = adding

if something says it's doing something more than once, add it the number of times it's doing that thing. (You can also multiply it by that number but the adding way is a bit easier to understand and explain)

<u>Elevator 1:</u>

6 + 7 + 7 - 10 = 10

<u>Elevator 2:</u>

20 - 5 - 5 - 5 + 12 = 17

Elevator 2 ends on a higher floor (reasoning above)

Math help what is the answer will give brainliest.
artcher [175]
The two equations are
x + y = 7
and
4x + 2.5y = 22
the first equation can be solved for x to be
x = 7 - y
next you can substitute x in the second equation
4(7 - y) + 2.5y = 22
Distribute 4 to everything in the parentheses
28 - 4y + 2.5y = 22
combine like terms:
28 - 1.5y = 22
subtract 28 from both sides of the equation
- 1.5y =  - 6
divide both sides by -1.5
y =  4
plug this in to the original equation of x+y=7
x + 4 = 7
subtract 4 from both sides.
x = 3
