4 possibilities:
a) \(2x+3x-5+9x+\frac{1}{2}=?\)
Combine like terms --> \(14x-4.5=?\)
b)\(2(x+3x-5+9x+\frac{1}{2})=?\)
Distribute --> \(2x+6x-10+18x+1=?\)
Cobine like terms --> \(26x-9=?\)
c)\(\frac{2x+3x-5+9x+1}{2}=?\)
Combine like terms: \(\frac{14x-4}{2}=?\)
Simplify: \(7x-2=?\)
d)\(2(\frac{x+3x-5+9x+1}{2})=?\)
The 2 as the coefficient cancel out with the 2 in the denominator: \(x+3x-5+9x+1=?\)
Combine like terms:\(13x-4=?\)
Really hope one of those answered your question!
