Substitution in Algebra
In Algebra "Substitution" means putting numbers where the letters are:
If you have: x-2 and you know that x=6 ... then you can "substitute" 6 for x: 6-2=4
More examples:
If x=5 then what is 10/x + 4 ?
Put "5" where "x" is: 10/5 + 4 = 2 + 4 = 6
If x=3 and y=4, then what is x2 + xy ?
Put "3" where "x" is, and "4" where "y" is: 32 + 3×4 = 9 + 12 = 21
If x = -2, then what is 1-x+x2 ?
Put "(-2)" where "x" is: 1 - (-2) + (-2)2 = 1 + 2 + 4 = 7
