how to solve it

OpenStudy (anonymous):

every time you see an "x" put 5 there

OpenStudy (jhannybean):

Yeah.... @DDCamp is right. \[\large 7(\color{red}5-8)-3\]\[\large 7(\color{red}{-3})-3\] multiply it with the 7 then subtract the result from -3.\[\large \color{red}{-21}-3\]

OpenStudy (anonymous):

so the answer is 24

OpenStudy (anonymous):

OpenStudy (jhannybean):

To simplify it, take out the negative and add the two numbers.\[\large -(21+3)\]
