7-x/3=4-xthe answer is -9/2 but pls explain me how

Answer»

Hope this HELPS:

Step-by-step explanation:

7 (-x)/3 = 4-x

We multiply everything by 3 in order to make the fraction go away.

21 -x = 12 -3x

We should move all the x and all the whole numbers to opposite sides.

9=-2x

That is why x is -9/2
