Donnie is 7 years old. Donnie's age is 3 years less than half of Ana's age. The relationship between their ages can be modeled by the equation 12x−3=7, where x is Ana's age. How old is Ana?

I think Ana might be 9 ? I’m sorry if I am wrong I don’t even think I did the math correctly

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

5\16 x 2\5 = 10/80simplify to 1/80
