Answer:
-(19/5) or -3.8
Step-by-step explanation:
In this case we put the like terms together as follows
-4w+(7/2)w=(-3/2)-(2/5) note the change of signs when the equal sign. + changes to - and -changes to +.
Therefore -(1/2)w=-(19/10)
dividing both of the equal sign by -(1/2) gives:
w=-(19/10)/-(1/2)
w=-(19/5) or -3.8
