Each president has a presidential number (between 1-44). Solve for X each time. Example: Jefferson[X] - Van Buren = Jackson would be 3x-8=7 (add 8 to both sides) which equals 3x=15 which (divide both sides by 3) x="5". Our 5th president is Monroe- answer: "James Monroe"
Remember PEMDAS.
HINT: For answers with TWO X-values, consider: can there be a negative number president?
3x^2+15x-6x-30 is (via factoring and grouping): 3x(x+5)-6(x+5) is (3x-6)(x+5) is x=-5 and x=6/3=2 There can't be a negative 5th president, so the answer is 2 (John Adams)
[SQUARE ROOT of (Monroe * John Adams)(Reagan((-)Washington+Monroe)] [X] = Reagan^John Adams
[Square Root of (5*2)(40(-1+5))]x=40^2 is [Square Root of (10)(40(4))]x=1600 is [Square Root of (1600)]x=1600 is [40]x=1600 is x=40
X + John Adams = Harding
x+2=29 is x=27
[SQUARE ROOT of (Madison + X)] = Monroe
[Square Root of (4+x)]=5 is (square both sides to get rid of the square root) x+4=25 is x=21
Jackson (X - Jefferson) - Monroe(X) = (-)Jackson
7(x-3) - 5x = -7 is 7x-21-5x = -7 is 2x-21+21 = -7+21 is 2x=14 is x=7 (Andrew Jackson)
(Van Buren / Madison)(Truman * John Adams) / (Jefferson * Washington) = John Adams(X)
(8/4)(33*2)/(3*1)=2x is x=22
X^John Adams - John Adams(X) - (Reagan * John Adams)=0
x^2-2x-(40*2)=0 is x^2-2x-80=0 is (x-10)(x+8)=0 is x=10 and x=(-8); There can't be a negative 8th president, so the answer is 10 (John Tyler)
[Tyler(Van Buren + Taft) + Lincoln](Jackson - Monroe - John Adams) + Washington = X
[10(8+27)+16](7-5-2)+1=x is [350+16](0)+1=x is 0+1=x is x=1
