Answer: the equation would be 5n=1,500
Step-by-step explanation:
5 dollars per N (student) they need to make 1,500 so you need to find n
( to find N do 1,500 divided by 5 = 300
148 you can use that as your answer
Answer: y = -5; x = -2
Step-by-step explanation:
- 5y – 10x=45
- 3y + 10x = -5
Combining both equations
-8y = 40
y= 40/ -8
y = -5
Substitute y = -5 into any of the equations to get the value of x
-5 (-5) - 10x = 45
25 -10× = 45
-10x =45 -25
-10× = 20
Divide both sides by -10
x = -2
