Answer:
X=7
Step-by-step explanation:
STEP 1: Simplify both sides of the equation
7x + -10 + 2x =39 + 2x
(7x + 2x) + (-10) = 2x + 39 (combine like terms)
9x -10 = 2x + 39
step 2: Subtract 2x from both sides
9x -10 - 2x = 2x + 39 - 2x
7x - 10 =39
Step 3: Add 10 to both sides.
7x - 10 + 10 = 39 + 10
7x = 49
Step 4: Divide both sides by 7.
7x/ 7 = 49/7 <u> x=7</u>

C=1500+4x where x is cds, C is cost
R=10x where R is revenue
then, P=R-C
P=10x-1500-4x
P=6x-1500
set P=0
1500=6x
x=250
check, C=1500+4*250, R=10*250
C=250, R=250
They need to sell 250 cds before they make profit
