    Miranda: x +y = 5 owen: 3x +2y = 12 x = apples y = oranges ...now solve simultaneous equation... i'd recommend substitution

    Miranda: x +y = 5 Equation 1 Owen: 3x +2y = 12 Equation 2 rearrange equation 1 to get y = 5 - x sub the new equation into equation 2 3x + 2y = 12 3x + 2(5 -x) = 12 so x = ...?

    Ok.. so far to figure it out I subtracted 3 and subtracted it from the 12... and got x+2(5-x)=9

    3x + 2y = 12 3x + 2(5-x) = 12 3x + 10 -2x = 12 3x - 2x = 12 - 10 x = 12-10 x = 2 so mirinda originally has 2 apples and as she starts out with 5 fruit, she also has 3 oranges

    maybe i described it poorly at the start x = number of apples Mirinda has y = number of oranges Mirinda has and yeah, use BODMAS to do the correct order of operations

    let the number of apple and oranges bought by miranda be x and y respectively,Therefore, x+y=5(Miranda) and, 3x+2y=12(owen) y=5-x....Substituting this in Owen's equation.3x+2(5-x)=12 will be,3x+10-2x=12 Group like terms together x=12-10 x=2 and y=5-2=3 Therefore,Miranda has 2 Apples
