Question

Solve for w

-4w+(2/5)=-(7/2)w-(3/2)

Answer 1

-(19/5) or -3.8

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
