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)

black/brown

step-by-step explanation:

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
