Question

How many solutions?

y−2=x

−x=2−y

Answer 1

infinite

Explanation:

the first equation (y-2=x) becomes y=x+2 when you add 2 to both sides

the second equation (-x=2-y) also becomes y=x+2 when you add y and x to both sides

• -x = 2-y
• y-x=2
• y=x+2

since both equations are the same the number of solutions is infinite
