addtion of two equations with out using functions in matlab

main.m
% Define the equations
equation1 = "2x + 3y = 5";
equation2 = "4x - 2y = 7";

% Extract coefficients from equation1
coefficients1 = sscanf(equation1, '%dx + %dy = %d');

% Extract coefficients from equation2
coefficients2 = sscanf(equation2, '%dx + %dy = %d');

% Perform addition
resultCoefficients = coefficients1 + coefficients2;

% Construct the resulting equation
resultEquation = sprintf('%dx + %dy = %d', resultCoefficients(1), resultCoefficients(2), resultCoefficients(3));
disp(resultEquation);
