Question

slove for x: 5x-7/3k-9 = -6/7​

Answer 1

Answer:

(5x-7)7 = -6(3k-9)

35x-49 = -18k+ 54

35x = -18k + 54 +49

35x = -18k+ 103

X = (-18k+103)/35

Answer 2

Step-by-step explanation:

Simplifying 5k + 7 = -3k + -9 Reorder the terms: 7 + 5k = -3k + -9 Reorder the terms: 7 + 5k = -9 + -3k Solving 7 + 5k = -9 + -3k Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '3k' to each side of the equation. 7 + 5k + 3k = -9 + -3k + 3k Combine like terms: 5k + 3k = 8k 7 + 8k = -9 + -3k + 3k Combine like terms: -3k + 3k = 0 7 + 8k = -9 + 0 7 + 8k = -9 Add '-7' to each side of the equation. 7 + -7 + 8k = -9 + -7 Combine like terms: 7 + -7 = 0 0 + 8k = -9 + -7 8k = -9 + -7 Combine like terms: -9 + -7 = -16 8k = -16 Divide each side by '8'. k = -2 Simplifying k = -2
