Equations with variables on both sides 9e+4=14+8e

U wanna get the variables on one side and everything else on the other side.

 9e + 4 = 14 + 8e we will subtract 8e from both sides
-8e               - 8e

e + 4 = 14            ...now we subtract 4 from both sides
    - 4     -4

e = 10

and u can check ur answer by subbing it back into the original equation...
9e + 4 = 14 + 8e
9(10) + 4 = 14 + 8(10)
90 + 4 = 14 + 80
94 = 94 (correct)

so ur answer is : e = 10
