Question

What is the answer to 3k-(-4)=22

Answer 1

Explanation:

This will result to 3k+4=22 because minus times minus is plus

Therefore, 3k=22-4, when +4 crosses over the equals to sign it becomes -4

=> 3k=18

=> Divide both sides by 3 to get k

=> k=6

Answer 2

k = 6

Explanation:

Given equation: 3k - (-4) = 22

Step 1: Simplify.

`\begin{aligned} 3k - (-4) &= 22\\ \implies3k + 4 &= 22\end{aligned}`

Step 2: Subtract
`4` from both sides.

`\\\begin{aligned} 3k + 4 -4 &= 22-4\\\implies 3k &= 18\end{aligned}`

Step 3: Divide both sides by
`3`.

`\\\begin{aligned}(3k)/(3) &= (18)/(3)\\\implies k&=6\end{aligned}`

Step 4: Check your work.

`\begin{aligned}3(6) - (-4) &= 22\\18+4&=22\\22&=22\ {\checkmark}\end{aligned}`
