Answer:
k = 3/4
Step-by-step explanation:
Given -
an equation = 5x + 3y - 7 = 0
value of x = 2k-1 and y = 2k
To find -
The value of k
Solution -
x = 2k - 1
y = 2k
5x + 3y - 7 = 0
=> 5(2k-1) + 3(2k) - 7 = 0
=> (5×2k) - (5×1) + (3×2k) - 7 = 0
=> 10k - 5 + 6k - 7 = 0
=> 10k + 6k -5 -7 = 0
=> 16k -12 = 0
=> 16k = 12
=> k = 12/16
=> k = 3/4
Hence the value of k = 3/4.
You can check the answer.
hope it helps.
