To simplify the expression 9/8k + 6/6, we first need to find a common denominator, which in this case is 8k. We then rewrite the fractions with the common denominator: (9/8k) + (6/8k). Combining the fractions gives us (9 + 6) / 8k = 15 / 8k. Therefore, the simplified expression is 15/8k.
16k
k = 8k + 28Subtract '8k' from each side of the equation:-7k = 28Divide each side by '-7' :k = -4
k=8k+28 k-8k=28 -7k=28 k=-(28/4) k=-4
8k = 6k - 26 8k - 6k = 6k - 6k - 26 2k = -26 2k / 2 = -26 / 2 k = -13. The answer is k = -13.
