Complete the statements to solve for x.

by the converse of the side-splitter theorem, if jk/kl = , then km ∥ jn.

substitute the expressions into the proportion: startfraction x minus 5 over x endfraction = startfraction x minus 3 over x + 4 endfraction.

cross-multiply: (x – = x(x – 3).

distribute: x(x) + x(4) – 5(x) – 5(4) = x(x) + x(–3).

multiply and simplify: x2 – x – = x2 – 3x.

solve for x: x = .
