VERY HARD: using Simultaneous equations solve the following:
1.) x + y = 5
2.) x-y = 1
Find what X and y are.
use either the elimination method OR the substitution method.

• x = 5, y = 0
• x = 2, y = 3
• x = 4, y = 1
• x = 3, y = 2

if substitution is one method of solving Simultaneous Equations what is another?

if elimination is one way of solving Simultaneous Equations what is the other?

Which method of simultaneous equation solving do you find easier?

• x = 5, y = 2
• x = 3, y = 4
• x = 4, y = 3
• x = 6, y = 1

• x = 4.1, y = 0.8

• x = 2.2, y = 2.1

• x = 10.2 , y = 1.4

• x = 3.6, y = 1.6
