Asemmisa {{asɛmmisaAhyɛnsode}}

1.

What is the solution?
5x = 15 – 5y
8y + 26 = 2x

Asemmisa {{asɛmmisaAhyɛnsode}}

2.

What type of lines are #1? (Hint: what would you see on a graph? Intersecting lines, parallel lines, same line?)

Asemmisa {{asɛmmisaAhyɛnsode}}

3.

What is the solution?
2x – 6y + 9z = -8
5x + y + 2z = 10
3x + y – 8z = -28

4.

What type of lines are #3? (Hint: what would you see on a graph? Intersecting lines, parallel lines, same line?)

Asemmisa {{asɛmmisaAhyɛnsode}}

5.

What is the solution?
3x – 9y = 9
4x – 12y = 36
