How do you solve simultaneous equations maths
WebSolve Multivariate Equations and Assign Outputs to Variables Solve the system of equations. When solving for more than one variable, the order in which you specify the variables defines the order in which the solver returns the solutions. Assign the solutions to variables solv and solu by specifying the variables explicitly. WebIn simple terms, the solution to a pair of simultaneous equations is the x and y values of the coordinates of the point at which the graphs cross or intersect. The example below shows this. Solving Graphically For each equation, find coordinates for two points on the graph.

WebI'll get you started. Take the 2nd equation and add 3x to both sides to isolate "y". y = 3x+3 Now, substitute this value of "y" into the first equation. 3(3x+6) + 2x = 7 You can now solve for "x". Once you have the value of "x", use it to calculate the value of "y". Hope this helps. Comment back if you have questions.
