    HINT: substitute the value of y from the 2º equation into the first one

    replace y in first equation by 2nd one |dw:1433538776999:dw| after that simple algebra solve for c

    how about to solve it instead guessing \[\huge\rm -x-2=4x+3\] solve for x or to check an answer replace x and y by order pair if both sides are equal then that order pair is ur answer

    yes right \[\huge\rm -(-1)-2=4(-1)+3\] replace x by -1 solve both sides if both sides are equal then your answer is right :-)

    yes right \[\huge\rm -(-1)-2=4(-1)+3\] solve left side -1 times -1= ?? and then add -2
