Answer:
Step-by-step explanation:
x+y=3
graphing the equation by X intercept (3,0) and Y intercept (0,3)
y=2x-15
graphing the equation with slope = positive 2
and Y intercept = -15
and graphs of these lines are given as follows
solution is given by (6,-3)
Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
x + y = 3
x = 3 - y
y = 2x - 15
y = 2(3 - y) - 15
y = 6 - 2y - 15
y = -2y - 9
3y = -9
y = -3
y = 2x - 15
-3 = 2x - 15
-2x = -12
x = 6
So...
The answer is: (6, -3)
