Use substitution to solve the linear system of equations.
x=4
-y=1/2x

(4, -2)
(-2, 4)
(4, 2)
(2, -4)

The solution is (4,-2)

Step-by-step explanation:

Given system of equations:

To solve the system of equations using substitution.

Solution:

We will substitute the value of given in the first equation in the second equation to solve for .

Substituting in second equation.

Multiplying both sides by -1 to isolate positive on the left.

[Two negatives multiply to become positive]

So, the solution is and .

The solution in order pair is  (4,-2)

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

step-by-step explanation:

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
