Question

I am A father who needs the answer to make sure my kids did it right. Thank you Use mental math to solve each equation. Equations Question Question #1) 16 + x = 20Question #2) x - 4 = 6Question #3) 2x = 22Question #4) x divided by 3 = 8Question #5) 5x = 10

Answer 1

Answer:

$\begin{gathered} 1)\text{ x=4} \\ 2)\text{ x=10} \\ 3)\text{ x=11} \\ 4)\text{ x=24} \\ 5)\text{ x=2} \end{gathered}$

Step-by-step explanation:

To solve these simple equations use inverse operations to solve equations.

*Addition and subtraction are inverse operations, like multiplication and division.

Question #1.

$\begin{gathered} 16+x=20 \\ x=20-16 \\ x=4 \end{gathered}$

Question #2.

$\begin{gathered} x-4=6 \\ x=6+4 \\ x=10 \end{gathered}$

Question #3.

$\begin{gathered} 2x=22 \\ x=\frac{22}{2} \\ x=11 \end{gathered}$

Question #4.

$\begin{gathered} \frac{x}{3}=8 \\ x=8\cdot3 \\ x=24 \end{gathered}$

Question #5.

$\begin{gathered} 5x=10 \\ x=\frac{10}{5} \\ x=2 \end{gathered}$
