Question

6x + 3 = 15

Answer 1

x=2

Answer 2

Since this is a Two Step Equation we must start with the addition part of the problem, and get that out of the way

\(\sf \large \color{magenta}{6x~+~3~=~15}\)

\(\sf \large \color{magenta}{6x~+~3~-~3~=~15~-~3}\)

Answer 3

Take 3 from both sides, divide both sides by 6

Answer 4

What is 3 - 3 and 15 - 3?

Answer 5

Listne to Sam, not me, hes better at explaining

Answer 6

3 - 3 = 0 and 15 - 3 = 12, so we plug in 0 and 12 where 3 - 3 was and 15 - 3 like so:

\(\sf \large \color{magenta}{6x~+~0~=~12}\)

Since Zero is nothing we can take that out of the problem

\(\sf \large \color{magenta}{6x~=~12}\)

Answer 7

Now we have to take care of the \(\sf \large \color{magenta}{6x}\), so we take \(\sf \large \color{magenta}{6}\) and divide it on both sides of the problems..

\(\sf \large \color{magenta}{6x/6~=~12/6}\)

Answer 8

\(\sf \large \color{magenta}{6x/6 = x}\) and \(\sf \large \color{magenta}{12/6 ~=~2}\), so now our equation looks like this

\(\sf \large \color{magenta}{x~=~2}\)

Answer 9

And that is our answer
