Question

if x=2k+1 and y=k is a solution of the equation 5x+3y-7=0,find the value of k​

Answer 1

SOLUTION

x = 2k + 1 and y = k

(putting the value in the given equation)

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

10k + 5 + 3k -7 = 0

13k = 2

k = 2/13

THEREFORE , THE VALUE OF K IS 2/13

Answer 2

$\bf{\huge{\underline{\boxed{\rm{\red{Answer:}}}}}}$

Given equation :-

• 5x + 3y - 7 = 0

Given :-

• Value of x = 2k + 1
• y = k

To find :-

• Value of k in the equation.

Solution :-

The solve this equation, we will simply plug in the given values of x and y in the equation.

Let's begin!

5x + 3y - 7 = 0

Substitute the values of x and y

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

10k + 5 + 3k - 7 = 0

Bring the terms together,

10k + 3k - 7 + 5 = 0

13k - 2 = 0

13k = 2

$\bf\large\frac{13}{2}$ = k

•°• Value of k = $\bf\large\frac{13}{2}$
