Answer 7

Expression Calculator evaluates an expression in a given context. Context of evaluation is specified by a comma separated list of equations. Both symbolical and numerical computations are supported. Calculations with complex numbers are also supported. If the intent is for the Expression Calculator to compute a numberical answer, then context should contain sufficient number of equations to resolve all variables in your expression. Expression 4*(x+y)-7 = 4*y+4*x-7 Copy to clipboard
4y+4x−7 Expression x=2[y=7*andz=6]

Answer 10

yea it helped meah

Answer 11

You didn't need to distribute it, that was unnecessary.
\[4(x+y)-7\]\[4(2+7)-7\]\[4\times9-7\]Can you simplify that?
