Question

X - y = 1
x+y=3 please using graphical method
​

Answer 1

X is 2, Y is 1.

Explanation:

say x is 2 and y is 1.

2 - 1 = 1

2 + 1 = 3

Answer 2

(2, 1)

Explanation:

To solve this using the graphical method, you want to graph each equation. Once you have graphed the equations, you need to locate the point of intersection. This is the solution to the system of equations.

To graph these equations, you can write the equation as is or convert to slope-intercept form: y = mx + b.

x - y = 1

Add y to both sides.

x = y + 1

Subtract 1 from both sides.

x - 1 = y

or

y = x - 1

x + y = 3

Subtract x from both sides.

y = -x + 3

These are your two equations.

Plug these into a graphing calculator or an online grapher.

From the graph, we can see that the point of intersection is at the coordinate (2, 1).

This is your solution.

Hope this helps!
