Did you know?
WebThe inputs to solve are a vector of equations, and a vector of variables to solve the equations for. sol = solve ( [eqn1, eqn2, eqn3], [x, y, z]); xSol = sol.x ySol = sol.y zSol = sol.z. xSol = 3 ySol = 1 zSol = -5. solve returns the solutions in a structure array. To access the solutions, index into the array. WebLearn about systems of equations using our free math solver with step-by-step solutions.
WebOne way you can do that is by multiplying the top equation by 5 and multiplying the bottom equation by 3 because then, you could easily cancel out the 15 (top equation) and the -15 (bottom equation) and solve the rest of the equation accordingly. >>> 5x + 3y = 12 4x - 5y = 17 5x + 15y = 12 4x - 15y = 17 5x = 12 4x = 17 9x = 29 x = ~3.22 (Then ...
