Given,
x= 2k +1
y = k,
To Find,
k
solution:-
5x + 3y = 7
5(2k +1) + 3(k) = 7. [from given]
10k + 5 +3k = 7
13k = 7 -5
13k = 2
k = 2/13.
hope this helps you.....!!

◐ 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
