Hello!
1. 2=e-1
First, you switch sides.
[tex]e-1=2[/tex]
Then, you add 1 from both sides of an equation.
[tex]e-1+1=2+1[/tex]
Add by the numbers.
[tex]2+1=3[/tex]
[tex]\boxed{e=3}[/tex], is the correct answer.

2. r-3=1
First, you add by 3 both sides of an equation.
[tex]r-3+3=1+3[/tex]
Add by the numbers.
[tex]1+3=4[/tex]
[tex]\boxed{r=4}[/tex], is the correct answer.

3. z-6.3=2.1
First, you add by 6.3 both sides of an equation.
[tex]z-6.3+6.3=2.1+6.3[/tex]
Add by the numbers.
[tex]2.1+6.3=8.4[/tex]
[tex]\boxed{z=8.4}[/tex], is the correct answer.

4. t-9.25=5.5
First, you add by 9.25 both sides of an equation.
[tex]t-9.25+9.25=5.45+9.25[/tex]
Simplify.
[tex]=14.7[/tex]
[tex]\boxed{t=14.7}[/tex], is the correct answer.

5. k-32.9=16.5
First, you add 32.9 both sides of an equation
[tex]k-32.9+32.9=16.5+32.9[/tex]
Add by the numbers.
[tex]32.9+16.5=49.4[/tex]
[tex]\boxed{k=49.4}[/tex], is the correct answer.
