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.
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
9k - 1 = k - 25 Subtract 1k from both sides: 8k - 1 = -25 Add 1 to both sides: 8k = -24 Divide both sides by 8: k = -24/8 = -3
