Answer:
Your question seems inaccurate. Sorry,please give the correct question.
Answer:
The answer to your question is 1.- (-3, 4) 2.- (3, 1) None of the choices
Step-by-step explanation:
1.- The solution of a system of equation by the graph method is the point in which the lines cross. In this graph we observe that this point is approximately
(-3, 4).
2.-
Equation 1 x + y = 4
Equation 2 x - y = 2
Solve by the combination method
x + y = 4
x - y = 2
2x 0 = 6
2x = 6
Solve for x
x = 6/2
x = 3
Substitute x in equation 1 to find y
3 + y = 4
Solve for y
y = 4 - 3
y = 1
Solution (3, 1)
It can save time from doing number crunching and analysis because it's an easy to see visual.
