Answer:
x = -X OR x = 0
Step-by-step explanation:
I don't know if the capital 'X' was a different variable, so I did both calculations.
2(x - 3) + 9 = 3(x + 1) + X
= 2x - 6 + 9 = 3x + 3 + X
= 2x + 3 = X + 3x + 3
= -x = X
= x = -X
2(x - 3) + 9 = 3(x + 1) + x
= 2x - 6 + 9 = 3x + 3 + x
= 2x + 3 = 4x + 3
= -2x = 0
= x = 0
Subtract 5 from both sides then you get -3r+9=-4r then add 3r to both sides then you get 9=-1r then divide both sides by -1 and you get r=-9
Price for company A:
p(A) = 10 + 5*h
Price for company B:
p(B) = 7*h
,where h is the hours.
To find the hours after which the prices for both are going to be the same, we set the price for A equal to the price of B and calculate h.
10 + 5*h = 7*h <=>
2*h = 10 <=>
h = 10/2 <=>
h = 5 hours
