Answer 2

Hello!

1. 2=e-1

First, you switch sides.

$e-1=2$

Then, you add 1 from both sides of an equation.

$e-1+1=2+1$

Add by the numbers.

$2+1=3$

$\boxed{e=3}$, is the correct answer.

2. r-3=1

First, you add by 3 both sides of an equation.

$r-3+3=1+3$

Add by the numbers.

$1+3=4$

$\boxed{r=4}$, is the correct answer.

3. z-6.3=2.1

First, you add by 6.3 both sides of an equation.

$z-6.3+6.3=2.1+6.3$

Add by the numbers.

$2.1+6.3=8.4$

$\boxed{z=8.4}$, is the correct answer.

4. t-9.25=5.5

First, you add by 9.25 both sides of an equation.

$t-9.25+9.25=5.45+9.25$

Simplify.

$=14.7$

$\boxed{t=14.7}$, is the correct answer.

5. k-32.9=16.5

First, you add 32.9 both sides of an equation

$k-32.9+32.9=16.5+32.9$

Add by the numbers.

$32.9+16.5=49.4$

$\boxed{k=49.4}$, is the correct answer.
