z x 2y What can we say about this?
2y = x = 2x 2y 3z z = y =
2y = 3x + 4z Can you draw this?
3x – z = 2y Make x the subject (x = ....)
True or False? z = x + 2y + g3 x + 2y = 3z - g
x – 2y = 3z Can you draw this?
Draw these and find 3 other equations for each: 3x + 2y + 6 = 12 12 = 2z - 5 f + 5 = g + 3 2x – 4 = 4 x – 5 = y - 3
