WebExample 1 Write an equation equivalent to x + 3 = 7 by subtracting 3 from each member. Solution Subtracting 3 from each member yields x + 3 - 3 = 7 - 3 or x = 4 Notice that x + 3 = 7 and x = 4 are equivalent equations since the solution is the same for both, namely 4. WebThe solve function solves equations. To use it, first specify some variables; then the arguments to solve are an equation (or a system of equations), together with the variables for which to solve: sage: x = var('x') sage: solve(x^2 + 3*x + 2, x) [x == -2, x == -1] You can solve equations for one variable in terms of others:
WebExample: solve for x: 2xx β 3 + 3 = 6x β 3 (xβ 3) We have said xβ 3 to avoid a division by zero. Let's multiply through by (x β 3): 2x + 3(xβ3) = 6. Bring the 6 to the left: 2x + 3(xβ3) β 6 = 0. β¦
