Explanation:
#64x + 2(-9 - 7) = 32#
#64x + 2(-16) =32 -># the#9# and#7# are both negatives, which caused the#-16# .
#64x-32=32 -># the#2# and#-16# were multiplied to create#-32#
#64x=64 -># the#-32# was added to the right to create#64# .
#x=1#
In order to make sure it all makes sense, plug in the
#64(1) +2 (-9 - 7) =32#
#64 + 2 (-16) =32#
#64 -32 = 32#
#32=32#
It all seems to check out perfectly fine.
