Solving simultaneous Equation
There are different methods to solve simultaneous equations and they are:
Substitution Method
Elimination Method
Graphical Method
We are given the simultaneous equation as:
y = 4x + 3
y = -x - 2
For graphical method, we will find the value of y for specific values of x for each equation and plot both of them. The point where both lines meet is the coordinate of the solution
