The sum of three numbers is 2. the first number minus the second plus the third is negative 2−2. the first minus the third is 22
iogann1982 [59]

x is the 1st number, y is the 2nd number, z is the 3d number.

x+y+z = 2

x - y + z= -2

x - z = y +22 -----> x-y-z=22


x+y+z = 2

<u>x - y + z= -2</u>

2x + 2z =0

x + z = 0

x = -z


x - y + z= -2 and x = -z

-z - y + z = -2, y =2


x-y-z=22 and x = -z, and y = 2 -----> x -2 +x = 22 --->2x = 24 ----> x = 12

x= -z -----> z = - 12

If you were to use the substitution method to solve the following system, choose the new
mestny [16]

Answer:

23x = -115

Step-by-step explanation:

In the substitution method, you must solve for 1 variable in 1 equation to replace it in the other equation. For the system:

2x - 7y = 4

3x + y = -17

Solving for y in the second equation:

y = -17 - 3x

Replacing y in the first equation:

2x - 7(-17 - 3x) = 4

2x + 119 + 21x = 4

23x = -115

This is the new equation after use the substitution method.

zalisa [80]

Answer:

A

Step-by-step explanation:

At the rate of 20 miles per hour, the car will travel 20 miles every 60 minutes, or a third of a mile every minute. This means that it will travel a mile in 3 minutes. For the car travelling at 30 miles per hour, it will travel half a mile every minute, or a mile every 2 minutes. 3-2=1 minute, or choice A. Hope this helps!
