Equation
X
Solution
Jackie Robinson+X=
Carmelo Anthony*
(Donovan Mcnabb+X)
42+x=15(5+x)
Multiply 15: 42+x=75+15x
Subtract x from both sides: 42=75+14x
Subtract 75 from both sides: -33=14x
Divide by 14 on both sides:x=-2.4
Cal Ripken Jr*
(Babe RuthX+Tim Duncan)=
Brett Favre
8(3x+21)=4
Multiply 8(3x+21): 24x+168=4
Subtract 168 on both sides: 24x=-164
Divide by 24 on both sides: x=-6.8
X+Matt Ryan=
Kobe BryantX+Dan Marino
x+2=24x+13
Subtract 13 from both sides: x-11=24x
Subtract x from both sides: -11=23x
Divide both sides by 23: x=-.47
Tom Brady^Derek Jeter+X=
Wayne Gretzky+Pedro Martinez
12^2+x=99+45
Square 12: 144+x=99+45
Add the right side: 144+x=144
Subtract 144 from both sides: x=0
Sidney Crosby+Chauncey Billups
- Lebron James =
Ben RoethlisbergerX
87+1-23=7x
Add 87+1: 88-23=7x
Subtract the left side: 65=7x
Divide both sides by 7: x=9.29
