Which facts could be applied to simplify this expression? Check all that apply. 5x+3y=(-x)+63
To add like terms, add the coefficients, not the variables.
First add 5x + X.
The simplified expression is 4x+3x+63
Only combine terms which contain the same variable.
The simplified expression is 5x+3x+63
