To solve the question we must know about the System of equations.

<h2>System of equation</h2>

<h2>Inconsistent System</h2>

A system of equations to have no real solution, the lines of the equations must be parallel to each other.

<h2>Consistent System</h2><h3>1. Dependent Consistent System</h3>

A system of the equation to be Dependent Consistent System the system must have multiple solutions for which the lines of the equation must be coinciding.

<h3>2. Independent Consistent System</h3>

A system of the equation to be Independent Consistent System the system must have one unique solution for which the lines of the equation must intersect at a particular.

The value of k should be 17 so that the system of equations gives infinite number of solutions.

<h2>Explanation</h2>

Given to us

35x + 14y = 119
5x +2y = k

As we know that for a system of equations to give an infinite number of solutions. the equations of the system must be either same or in ratio.

<h3>In Equation 1</h3>

$35x + 14y = 119,$

dividing both the sides of the equation by 7,

$\dfrac{35x + 14y}{7} = \dfrac{119}{7}\\\\
\dfrac{35x}{7}+\dfrac{14y}{7} = \dfrac{119}{7}\\
5x+2y = 17$

As already discussed the system of equations to give infinite number of solutions, the equations must be the same. therefore, comparing both the equations we see that the value of k should be 17.

Hence, the value of k should be 17, so that the system of equations gives infinite number of solutions.

<h3>Verification</h3>

As we can see in the below image on equating the value of k as 17, the line of the system of equations coincides, therefore, the system will have infinite number of solutions.
