Answer 1

Answer:

$a + b = 8 \\ c - d = 6 \\ a - + c = 13 \\ b + d = 8 \\ then \: first \: we \: add \: c + b = 14 \\ hen \: second \: we \: subtract \: c - b = 5 \\ then \: we \: add \: both \: c + b = 14 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: c - b = 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2c = 19 \\ so \: c = \frac{19}{2} \\ d = \frac{19}{2} - d = 6 \\ so \: d = \frac{7}{2} \\ a = 13 - \frac{19}{2} = \frac{7}{2} \\ so \: a \:= \frac{7}{2} \\ b = 8 - \frac{7}{2} = \frac{9}{2} \\ so \: a = \frac{7}{2} \\ b = \frac{9}{2} \\ c = \frac{19}{2} \\ and \: d = \frac{7}{2} \\ \\ mark \: as \: brainliest$
