OpenStudy (calculusxy):

@Mertsj Then what do I do

OpenStudy (mertsj):

The problem says that all together they made $27. Write and solve the equation that says that.

OpenStudy (calculusxy):

would it be like 4x+6x+8x=27

OpenStudy (mertsj):

yep

OpenStudy (calculusxy):

how do I solve for x for 8x?

OpenStudy (mertsj):

What is 4 + 6 + 8?

OpenStudy (calculusxy):

28

OpenStudy (mertsj):

Try again

OpenStudy (calculusxy):

18

OpenStudy (mertsj):
