Answer:
x = 5
y = 2
Step-by-step explanation:
In this question, you will have to use one of the equations to find the value of x in terms of y and substitute it in the other equation or vice versa.
y = 2x - 8
x - y = 3
Use the second equation to find the value of x in terms of y.
x - y = 3
x = y + 3
Now that we found that, we can substitute it in the other equation.
y = 2 (y + 3) - 8
y = 2y + 6 -8
y = 2y -2
y + 2 = 2y
y = 2
Now that we got y we can substitute the value in any of the equations to find x.
x - 2 = 3
x = 5
You can isolate the second equation and use substitution into the first equation:
x-y=3
x=y+3
y=2x-8
y=2(y+3)-8
y=2y+6-8
-y=-2
y=2
Plug this back into the second equation to solve for x:
x-y=3
x-2=3
x=5
So x=5 and y=2 is the answer.
x-y=3
x=y+3
y=2x-8
y=2(y+3)-8
y=2y+6-8
-y=-2
y=2
Plug this back into the second equation to solve for x:
x-y=3
x-2=3
x=5
So x=5 and y=2 is the answer.
