Question

Find any four solutions of linear equations 1)x+2y=4 2)2x+4y=12 3)x+y=5 4)2x-3y=12 5)5x-4y=-8

Answer 1

Answer:

Taking equations x+2y=4 and x+y=5

x+2y=4

x+y=5   subtract

----------------

y = -1

substitute y in any equation

x + y = 5

x - 1 = 5

x = 5 + 1

  = 6

therefore x = 6 and y = -1 ( answer )
