Answer:
pls say your question......I am also 7th
Step-by-step explanation:
Example: One-step equation with addition
Solve for kkk in the following equation:
k + 18 = 21k+18=21k, plus, 18, equals, 21
We want to get kkk by itself on the left hand side of the equation. Right now kkk has 181818 added to it, so we want to do the inverse and subtract 181818 from both sides of the equation. Here's what that looks like:
\begin{aligned} k + 18 &= 21 \\\\ k + 18 \blueD{- 18} &= 21 \blueD{- 18}~~\small\gray{\text{Subtract 18 from each side.}} \\\\ k &= \greenD{3}~~\small\gray{\text{Simplify.}} \end{aligned}
k+18
k+18−18
k
=21
=21−18 Subtract 18 from each side.

Solve for xxx in the following equation:
\dfrac x4 = 6
4
x
=6start fraction, x, divided by, 4, end fraction, equals, 6
We want to get xxx by itself on the left hand side of the equation. Right now xxx is being divided by 444, so we want to do the inverse and multiply by 444 on both sides of the equation. Here's what that looks like:
\begin{aligned} \dfrac x4 &= 6 \\\\ \dfrac x4 \cdot \blueD{4} &= 6 \cdot \blueD{4}~~\small\gray{\text{Multiply each side by four.}} \\\\ x &= \greenD{24}~~\small\gray{\text{Simplify.}} \end{aligned}
