Question

9x=18y-2.give 4 solutions of the equation

Answer 1

• 9x-18y=-2
• 9x+2=18y
• -18y=-9x-2
• 9x=18y-2 etc...

Answer 2

$9x = 18y - 2 \\ \\ 18y = 9x + 2 \\ \\ y = \frac{9x + 2}{18}$

$for \: x = 0 \\ y = \frac{9 \times 0 + 2}{18} = \frac{2}{18} = \frac{1}{9}$

$for \: x = 1 \\ y = \frac{9 \times 1 + 2}{18} = \frac{11}{18}$

$for \: x = 2\\ y = \frac{9 \times 2 + 2}{18} = \frac{20}{18} = \frac{10}{9}$

$for \: x = 3 \\ y = \frac{9 \times 3+ 2}{18} = \frac{29}{18}$

$four \: solutions \: are \: (0, \: \frac{2}{9} ), \: (1,\ \frac{11}{18} ), \ (2,\ \frac{10}{9} ),\ (3 ,\ \frac{29}{18} )$
