X = 4
First take 12x off both sides, so -7x=-28
The negatives cancel out, so 7x=28
Not find the hcf and divide by that.
Selection A is appropriate.
_____
20*1.1^n is the general expression for the cost n years in the future.
20*1.1^3 = 26.62 is the cost 3 years in the future.
Adding the systems of equations together, we get
2x=88
Dividing both sides by 2, we get x, or the number of women, to be 44.
Plugging that into either equation, we get
44-y=18. Adding y to both sides and subtracting 18, we get y, or the number of men, to be 26.
