Question

if x is equals to 2 k + 1 and Y is equals to K with solution of the equation 5 x + 3 Y - 7 is equals to zero find the value of k​

Answer 1

Answer:

$\frac{2}{13}$

Step-by-step explanation:

Given,

x = 2k + 1

y = k

$5x+3y-7=0\\By\ substituting\ values\ of\ x\ and\ y,\\ 5(2k+1)+3(k)-7=0\\=>10k+5+3k=7\\=>13k+5=7\\=>13k=7-5\\=>13k=2\\=>k=\frac{2}{13}$
