How would you go about solving this equation? -3(3y-3)-2y=8

OpenStudy (anonymous):

multiply the parentheses by -3 first

OpenStudy (anonymous):

so -9y+9-2y=8

OpenStudy (anonymous):

combine like terms

OpenStudy (anonymous):

-11y+9=8

OpenStudy (anonymous):

subtract 9 from both sides

OpenStudy (anonymous):

-11y=-1

OpenStudy (anonymous):

divide by negative 11 on both sides

OpenStudy (anonymous):

y=-1/-11
