5- x = 2

First we will need to isolate x .

We will subtract 5 from both sides.

==> 5-x -5 = 2- 5

==> -x = -3

Now we will multiply by -1.

==> -(-x) = -(-3)

==>x = 3

11= 2-3y

We need to isolate y.

First we will subtract 2 from both sides.

==> 11-2 = 2-3y -2

==> 9 = -3y

Now we will divide by -3.

==> 9/-3 = -3y/-3

==> -3 = y

==> y= -3.

5 - x = 2

subtract 5

-x = -3

divide by -1

x=3

11 = 2 - 3y

subtract 2

9 = -3y

divide by -3

y = -3

5 - x = 2

subtract 5

-x = -3

divide by -1 to get rid of the negative sing

x=3

11 = 2 - 3y

subtract 2

9 = -3y

divide by -3

-3 = y

5-x=2

11=2-3y

---------------

5-x=2

-x =2-5

-x=-3/*-1

x =3

11=2-3y

11-2=-3y

9 =-3y

-y= 9/3

-y=3/*-1

y=-3
