I need x+y=5 and y=2x-4solved algebraically

x = 3; y = 2

Step-by-step explanation:

x + y = 5

y = 2x - 4

Isolate the y in the first equation

y = 5 - x

y = 2x - 4

Substitute the values

5 - x = 2x - 4

Isolate the Variable

9 = 3x

Simplify

3 = x

Plug that into the first equation

3 + y = 5

Subtract 3 from both sides

y = 2

X=3, y=2 solved algebraicly
