Question

Tell what must be added to both sides of the equation x-11=19

Answer 1

Equations

To solve the equation, just isolate x.

x - 11 = 19

x = 19 + 11

x = 30

So, 11 has to be added to both sides of the equation.

Answer 2

+ 11

Explanation:

x - 11 = 19 ( add 11 to both sides )

x - 11 + 11 = 19 + 11

x = 30
