    Its a line that states values of variables, i guess

    A equation has two parts, right hand side and left hand side.

    Anything right of the '=' sign is right hand side

    I know, if you do something to the LHS you have to do the same to the RHS

    anyways back to the problem our hand: a+b=9 a−b=11

  34. Inopeki

    Yeah.

  35. FoolForMath

    we want to find a and b in terms of constants only.

  36. Inopeki
    • 2 years ago
    Best Response
    You've already chosen the best response.
    Medals 2

    So whats a constant?

  37. FoolForMath
    • 2 years ago
    Best Response

    How could we do that ?

  38. FoolForMath
    • 2 years ago
    Best Response

    Medals 2

    constant is something which value is fixed.

  39. Inopeki
    • 2 years ago
    Best Response
    You've already chosen the best response.
    Medals 2

    Ok, so we can subtract a from both sides to get b on the top one, right?

  40. FoolForMath
    • 2 years ago
    Best Response

    Medals 2

    Why don't we add the equations? like this \[ a+b+a-b=9+11\]

  41. Inopeki

  42. Inopeki
    • 2 years ago
    Best Response

    Well we can simplify that to a2=20, right?

  43. Inopeki
    • 2 years ago
    Best Response

    Medals 2

    Cause the b's cancel eachother out

    Best Response

    yes.

  45. Inopeki
    • 2 years ago
    Best Response
    You've already chosen the best response.

    And for a we can just divide both sides by 2 getting x=10

    Ok. Here's the solution ax - a = x - 1 ax - x - a = -1 ax - x = a - 1 x(a - 1) = a - 1 hence x = 1
