Answer 1

Answer:

value of k is -5/13

Hope it helps

Answer 2

◐ Given ◐

x = 2k + 1

y = k

is a solution of the equation 5x + 3y - 7 = 0

◐ To find ◐

Value of k

◐ Solution ◐

5x + 3y - 7 = 0

☯ Substitute the value of x and y

5(2k + 1) + 3(k) - 7 = 0

10k + 5 + 3k - 7 = 0

13k + 5 - 7 = 0

13k - 2 = 0

13k = 2

k = 2/13

∅ The value of k is ²⁄₁₃
