Video Summary

The transcript solves a word problem by turning the statements into equations. It defines Mariam’s amount as \(M = R + E - 13\) and Ria’s amount as \(R = 5 + E + M\). Then it substitutes the first equation into the second and simplifies. After canceling \(R\), the equation becomes \(0 = 2E - 8\). Adding 8 gives \(2E = 8\), so \(E = 4\). Therefore, Emma has <strong>4 dollars</strong>.
