Accepted Solution
A:
Answer: 5 Months Step-by-step explanation:$450 + $40x = $975-$45x-$20x (combine like terms)450 + 40x = 975 - 65x (perform inverse operations to get only the variable on one side, what is done to one side must be done to the other)450 + 40x + 65x = 975 - 65x + 65x450 - 450 + 105x = 975 - 450105x = 525 (divide both sides by 105)x=5
