Try each  answer into the equation in place of x and y 

2x +3y +4 = 15 


A) x = 6, y = 3

2x + 3y +4 = 15 
2(6) +3(3) +4 =___ (should equal 15 to be the answer) 
12 + 9 + 4 = 25 
The equation equals 25, not 15, so A is not the answer. 
 
B) x = 3, y = 5 

2x +3y +4 = 15
2(3) +3(5) +4 = ___ (Should equal 15 to be the answer) 
6 +15 +4 = 25
The equation equals 25, not 15, so B is not the answer 

C) x = 6, y = 4 
2x +3y +4 = 15 
2(6) +3(4) +4 =___ (should equal 15 to be the answer) 
12 + 12 +4 = 28
The equation equals 28, not 15, so C is not the answer 


D) x = 1, y = 3 

2x +3y +4 =15 
2(1) +3(3) +4 = ___ (should equal 15 to be the answer) 
2 +9 +4 = 15
The equation equals 15 so this would be the answer 

D (or the last option) x = 1, y = 3 is the answer to your question 

Hope this helps! :)

Unknown variables in Equations <br><br> 1. 7=w/14<br> 2.42/n=7<br> 3. 324/18=a
belka [17]

Answer:

w = 98

n = 6

a = 18

Step-by-step explanation:

Question 1)

7 = w/ 14

All you need to do is multiply each side by 14 to find w:

7(14) = W

W = 98

Question 2)

42/n = 7

For this one, first multiply each side by "n":

42 = 7n

and then divide both sides by 7:

N = 6

Question 3)

All you need to do for this question is divide 324 by 18 to find "a":

324/18 = a

a = 18

I hope this helps!
