I’ll say that you should use your calculator
Step-by-step explanation:
thank you very much.....
elimination means to get rid of one variable by altering the coefficients of variable (by multiplying and diving by some constant number)
in this case, if you just add the two equation, y gets cancelled you get 5x=20 or x=4
put it in any equation to get y (this works because both lines pass through the same point, so they must satisfy that point) to get y=2
The correct answer is letter D, Region D contains the solution for the system of inequalities.
