solve each one step equation
a. $x + 5 = 7$ \quad $x =$
b. $x - 3 = 12$ \quad $x =$
c. $\dfrac{x}{10} = 80$ \quad $x =$
d. $7x = 56$ \quad $x =$

Question

Accepted Answer

# Explanation:
## Part a: Solve $ x + 5 = 7 $
To isolate $ x $, we subtract 5 from both sides of the equation.
$$
\begin{align*}
x + 5 - 5 &= 7 - 5 \
x &= 2
\end{align*}
$$

## Part b: Solve $ x - 3 = 12 $
To isolate $ x $, we add 3 to both sides of the equation.
$$
\begin{align*}
x - 3 + 3 &= 12 + 3 \
x &= 15
\end{align*}
$$

## Part c: Solve $ \frac{x}{10} = 80 $
To isolate $ x $, we multiply both sides of the equation by 10.
$$
\begin{align*}
\frac{x}{10} \times 10 &= 80 \times 10 \
x &= 800
\end{align*}
$$

## Part d: Solve $ 7x = 56 $
To isolate $ x $, we divide both sides of the equation by 7.
$$
\begin{align*}
\frac{7x}{7} &= \frac{56}{7} \
x &= 8
\end{align*}
$$

# Answer:
a. $ x = 2 $
b. $ x = 15 $
c. $ x = 800 $
d. $ x = 8 $
