Answer:
Explanation:
to understand this
you need to know about:
- system of linear equation
- graphing system of linear equation
tips and formulas:
- when we have two linear equation to find the value of x and y is called the system of linear equation
- when we have graph, the solutions of system of linear equation are the coordinates of two lines cross together
let's solve:
since you can see at "tips and formulas" what linear equation is and what the solutions are when you have graph
if you see the graph attentively, you can see that the blue line and the red line cross together at (3,3) coordinates
therefore
the solution of the system of linear equation is
(x,y)=(3,3)
