1/2(4x)=-20 plz help and show work
2 answers:
X=10 because........
the opposite of 1/2=times 2
20 times 2=40
40 divided by 4=10, so
x=10
Ok so you would have to first get rid of the fraction. So you would multiply both sides by 2. As 2 is the reciprocal of 1/2.
2[1/2(4x)]= 2(-20)
^ So now the 1/2 would be cancelled out with the two. And don't forget to multiply the -20 by 2, too.
4x= -40
^ Now, you want to divide both sides by 4 to isolate x on one side. So ..
4x / 4= -40/4
^ The fours cancel each other out and -40 is divided by 4.
x = -10
^So x equals -10! hope this helped !!
