Question

write four solution of equation 4x+3y=7

please help me​

Answer 1

Answer:

$4x + 3y = 7 \\ 3y = 7 - 4x \\ y = \frac{7 - 4x}{3} \\ if \: x= 1 \: then \\ y = \frac{7 - 4(1)}{3} = \frac{7 - 4}{3} = 3 \\ if \: x = 2 \: then \: \\ y = \frac{7 - 4(2)}{3} = \frac{7 - 8}{3} = - \frac{1}{3} \\ if \: x = 0 \: then \\ y = \frac{7 - 4(0)}{3} = \frac{7}{3} \\ if \: x = - \frac{1}{2} \: then \\ y = \frac{7 - 4( \frac{ - 1}{2} )}{3} = \frac{7 + 2}{3} = \frac{9}{3} = 3$
