How to solve your question

Your question is

3

(

−

1

)

=

6

3(x-1)=6

3(x−1)=6

Solve

1

Distribute

3

(

−

1

)

=

6

{\color{#c92786}{3(x-1)}}=6

3(x−1)=6

3

−

3

=

6

{\color{#c92786}{3x-3}}=6

3x−3=6

2

Add

3

3

3

to both sides of the equation

=

6

3x-3=6

3x−3=6

−

3

+

3

=

6

+

3

3x-3+{\color{#c92786}{3}}=6+{\color{#c92786}{3}}

3x−3+3=6+3

3

Simplify

Add the numbers

Add the numbers

again

3

=

9

3x=9

3x=9

4

Divide both sides of the equation by the same term

3

=

9

3x=9

3x=9

3

3

=

9

3

\frac{3x}{{\color{#c92786}{3}}}=\frac{9}{{\color{#c92786}{3}}}

33x=39

5

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

=

3

x=3

x=3

Solution

=
