3- y/2 = 2(y + 7) can u plz show me the working out, thx

3 - y/2 = 2(y + 7)             Multiply by 2 to eliminate fraction
2(3) - y = 4(y+7)             Simplify
6 - y= 4y +28                  Move y over to the right
6 = 4y +28 +y                 Collect y terms, move 28 to the left
6-28 = 5y                        Simplify
-22 =5y                           Divide both sides by 5
-22/5= 5/5y                     Simplify
-22/5=y                           Rearange
y= -22/5

It is 198,87032,750 + 375 = 33145 so, we take the 6% and we make it a decimal (0.6) and multiply that, then that is your answer
