			<abstract xml:lang="en">
				<p>In solving various applied problems of mathematical physics, integral equations are increasingly used. This arouses interest in methods for solving such equations.</p>
<p>This article discusses an approximate method for solving the Fredholm integral equation of the first kind with a Fredholm kernel. The method is based on the approximation of the solution of an integral equation by a system of point potentials.</p>
<p>The method of point potentials is successfully used to solve a number of problems in mathematical physics. This is due to its algorithmicity and ease of use for a wide class of areas. These advantages remain for the method proposed in the article.</p>
<p>An approximate solution to the integral equation is sought in the form of a linear combination of point potentials. To determine the coefficients of this linear combination, a variational problem is constructed.</p>
<p>The convergence of the method is proved. For the numerical implementation, a stable algorithm based on the regularization of the initial variational problem is proposed. The problem of finding an approximate solution is reduced to a system of linear algebraic equations.</p>
<p>Using the proposed method, the problem of flowing around an infinitely thin plate with a potential flow of an ideal fluid, which reduces to the Fredholm integral equation of the first kind with a logarithmic kernel, is solved. The results of numerical calculations are presented.</p>
