Compute the values of X1, X2, X3, X4, X5, X6. x₁ => x2 = How to enter the solution: C 80 cars/h 50 cars/h X6 な D -<- 140 cars/h If the value of a variable is a number, just enter the number. If the value of a variable is a formula involving free variables, enter the formula. For example, if you obtain that x1 = 1-2x2 + 3x3 where x2 and x3 are free, then as to indicate subscripts of variables, and the value of x1 you should enter 1 - 2*x_2 + 3*x 3. Use the underscore If a variable is a free variable, enter the variable name as its value. For example, if x2 is a free variable, then you should enter X_2 to indicate multiplication. as the value of x2. x4 = x5 X3 x6= Consider the following diagram of one-way roads, with indicated traffic flow on some roads. Compute the values of X1, X2, X3, X4, X5, X6. How to enter the solution: 100 cars/h A X1 x2 − → X3 E C 50 cars/h 80 cars/h X4 B → 120 cars/h 40 cars/h *5 D-- 140 cars/h X6 If the value of a variable is a number, just enter the number. to indicate multiplication. If the value of a variable is a formula involving free variables, enter the formula. For example, if you obtain that x1 = 1-2x2 + 3x3 where x2 and x3 are free, then as the value of x1 you should enter 1 - 2*x_2 + 3*x_3 . Use the underscore _ to indicate subscripts of variables, and If a variable is a free variable, enter the variable name as its value. For example, if x2 is a free variable, then you should enter X_2 as the value of x2.
