Answer:
x = -24
Step-by-step explanation: Please brainliest!
Subtract 1/3 from both sides of the equation.
x/12 + 1/3 = 5/3
x/12 + 1/3 - 1/3 = -5/3 - 1/3
-----------------------------------------------------------
Simplify and subtract the numbers.
x/12 = 2
-----------------------------------------------------------
Multiply all terms by the same value to eliminate fraction denominators.
x/12 = -2
12 . x/12 = 12 (-2)
------------------------------------------------------------
Cancel multiplied terms that are in the denominator.
12 . x/12 = 12 (-2)
x = 12 (-2)
------------------------------------------------------------
Multiply the numbers.
x = 12 (-2)
x = -24
Answer x = -24
Answer: Charles bought a used car and later sold it for a 20% profit. If he sold it for $4680, how much did Charles pay for the car?
---------------------------
Let the price he paid equal "x".
EQUATION:
x + 0.20x = 4680
1.2x = 4680
x = $3900 (price he paid for the car.
Answer:
n = 15.5
Step-by-step explanation:
(4+n)/(43+n) =1/3
3(4+n)= 1*(43 + n)
12 + 3n = 43 + n
3n - n = 43 - 12
2n = 31
n = 31/2= 15.5
The first step would be :
E) 3x + (2x + 4) = -7
