Answer 2

Answer:

1)

3*1-y=2

We move all terms to the left:

3*1-y-(2)=0

determiningTheFunctionDomain -y-2+3*1=0

We add all the numbers together, and all the variables

-1y+1=0

We move all terms containing y to the left, all other terms to the right

-y=-1

y=-1/-1

y=1

3*2-y=2

We move all terms to the left:

3*2-y-(2)=0

determiningTheFunctionDomain -y-2+3*2=0

We add all the numbers together, and all the variables

-1y+4=0

We move all terms containing y to the left, all other terms to the right

-y=-4

y=-4/-1

y=+4

3*1.6-y=2

We move all terms to the left:

3*1.6-y-(2)=0

determiningTheFunctionDomain -y-2+3*1.6=0

We add all the numbers together, and all the variables

-1y+2.8=0

We move all terms containing y to the left, all other terms to the right

-y=-2.8

y=-2.8/-1

y=2+0.8/1

2)

2x-(-9)=3

We move all terms to the left:

2x-(-9)-(3)=0

determiningTheFunctionDomain 2x-3-(-9)=0

We add all the numbers together, and all the variables

2x+6=0

We move all terms containing x to the left, all other terms to the right

2x=-6

x=-6/2

x=-3

2x-(2)=3

We move all terms to the left:

2x-(2)-(3)=0

We add all the numbers together, and all the variables

2x-5=0

We move all terms containing x to the left, all other terms to the right

2x=5

x=5/2

x=2+1/2

2x-(-1)=3

We move all terms to the left:

2x-(-1)-(3)=0

determiningTheFunctionDomain 2x-3-(-1)=0

We add all the numbers together, and all the variables

2x-2=0

We move all terms containing x to the left, all other terms to the right

2x=2

x=2/2

x=1
