Answer:
K = 6
Step-by-step explanation:
Plug in what the letter equals to
Equation will look like:
2(11) = 4 + 3k or 3k + 4 = 2(11)
multiple the 2 by 11 and get 22
3k + 4 = 22 subtract the 4 so it can leave the 3k alone
22 - 4 = 18 now divide 3 from k and do it in the other side
18/3 = 6
so K = 6
First, find the value of the expression within the parentheses, which is 8x. Since x=1/4, 8x=8/4 or 2. Next, multiply this value by -3. -3*2=-6
