This shows that a system of equations may have one solution (a specific x,y-point), no solution at all, or an infinite solution (being all the solutions to the equation). You will never have a system with two or three solutions; it will always be one, none, or infinitely-many. Metric System Quiz; Measurement - Temperature. Converting Celsius to Fahrenheit I; ...

Online homework and grading tools for instructors and students that reinforce student learning through practice and instant feedback. Answer: (A) Given the form of the equation that we are given, it makes sense to go ahead and solve for the x and y intercepts. Solving for the y-intercept requires setting x = 0 in the above equation and then solving for y. Thus 15(0) − 3y = 60 which implies that y = −20.A system of linear equations a 11 x 1 + a 12 x 2 + … + a 1 n x n = b 1 a 21 x 1 + a 22 x 2 + … + a 2 n x n = b 2 ⋯ a m 1 x 1 + a m 2 x 2 + … + a m n x n = b m can be represented as the matrix equation A ⋅ x → = b → , where A is the coefficient matrix, Learn about systems of equations using our free math solver with step-by-step solutions.
