Question

What is the solution to (-7)=e/3+14

Answer 1

-7= e/3+ 14
⇒ -7 -14= e/3
⇒ -21= e/3
⇒ -21* 3= e
⇒ -63= e

Final answer: e= -63~

Answer 2

To work this out, we must use the balancing method - whatever we do to one side, we do exactly the same to the other

-7 = e/3 + 14
(-14) (-14)
-7 - 14 = -21

-21 = e/3
(x3) (x3)
-21 x 3 = -63
-63 = e

e = -63
