: complete to make the equation true. 42-24- 12+4-9

OpenStudy (anonymous):

I would put a variable (say "x") into the space and set the equation equal to 0. Then solve for "x".

OpenStudy (anonymous):

huh??

OpenStudy (anonymous):

try: 42 - 24 - (x) + 12 + 4 - 9 = 0 and solve for x.

OpenStudy (anonymous):

Nope, not 18. Try isolating the "x" to one side of the equation
