Answer:
k=2
Step-by-step explanation:
7[k+8]=70
First distribute the 7 into the k+8
7k+56=70
Then subtract the 56 on both sides since we want to isolate the variable
7k=14
Lastly divide each side by 7 to get the variable by itself and its value
k=2
We can check this by plugging 2 into the equation. We substitute for 2 in place of k.
7[2+8]=70
First do inside the brackets
7[10]=70
Next multiply
70=70
The equation is true so we know for sure that 2=k
