The solution to the system of equation is (3/2, -1/2)

<h3>System of equations</h3>

Given the following system of equations as shown;

(3x+y=4 .... * 4

2x-4y=5 ..... * 1

_______________

12x+4y=16

2x-4y=5

Add both equations

12x+2x = 16 + 5

14x = 21

x = 3/2

Substitute x = 3/2 into any of the equation to have;

2x-4y=5

2(3/2) - 4y = 5

3 - 4y = 5

-4y = 5 - 3

-4y = 2

y = -1/2

Hence the solution to the system of equation is (3/2, -1/2)

Dominik [7]
The answer to this question would be: D. <span>200>6P(8.00)+4S(5.00)
</span>

Michaela is planning a pizza party for 48 people and she uses 12-pack of soda and <span>8-slice pizza. That means the pack of soda she needs would be:
48 people/ (12soda/pack)= 4 pack

Then, number the pizza she needs:
48 people/ 8 (slice/pizza)=  6 pizza

She has $200 so the price she can afford should be lower than that. The function would be:
the money she has > number of pizza(price of pizza) + number of soda(price of soda)
</span>200>6P(8.00)+4S(5.00)

x=0

because you must

determine the undefined range

write all numerators above the common denomonator

multiply the parenthesis

collect the alike terms

remove parenthesis

eliminate the opposites collect the like terms

set the numerator equal to 0

divide both sides by 6

check if thesolution is the defined range

if so then you would find your answer X=0

A little help here? <br><br><br> Whats the value of X?
zubka84 [21]
You’d add 65+79 to get 144 then subtract that from 180 and get 36 so X would be 36 :) hope this helped!
