ALGEBRA PROJECT JUAN DIEGO GUTIERREZ,ISABELLA HERNANDEZ AND SOFÍA CASAS. 8B Cramers rule : • is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution. It expresses the solution in terms of the determinants of the (square) coefficient matrix and of matrices obtained from it by replacing one column by the vector of right hand sides of the equations. Ice Hockey problem • The admission at an ice hockey game is $15 for adults $11 for children. A total of 650 tickets were sold. Determine how many chidren’s tickets and how many adults’ tickets were sold in total of $8790 was colected • Steps: 1. Find the equations 2. Start using craimers rule 3. Find x 4. Find y 37.
