Step-by-step 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:
k = 6
Step-by-step explanation:
Given equation: 3k - (-4) = 22
Step 1: Simplify.
[tex]\begin{aligned} 3k - (-4) &= 22\\ \implies3k + 4 &= 22\end{aligned}[/tex]
Step 2: Subtract [tex]4[/tex] from both sides.
[tex]\\\begin{aligned} 3k + 4 -4 &= 22-4\\\implies 3k &= 18\end{aligned}[/tex]
Step 3: Divide both sides by [tex]3[/tex].
[tex]\\\begin{aligned}\dfrac{3k}{3} &= \dfrac{18}{3}\\\implies k&=6\end{aligned}[/tex]
Step 4: Check your work.
[tex]\begin{aligned}3(6) - (-4) &= 22\\18+4&=22\\22&=22\ {\checkmark}\end{aligned}[/tex]
