b)

$\sf \blue x \blue+ \blue5 \blue= \blue1 \blue0 \\ \sf\blue x \blue= \blue1 \blue0\sf \blue - \blue5 \\ \sf\blue x \blue= \blue 5$

c)

$\sf \blue2 \blue x \blue+ \blue x \blue= \blue2 \blue5 \\ \sf \blue3\blue x \blue= \blue2 \blue5\sf \\ \sf\blue x \blue= \frac \blue{25} \blue{3}$

d)

$\sf \blue a \blue+ \blue2 \blue= \blue2 \blue4 \\ \sf\blue a \blue= \blue2 \blue4\sf \blue - \blue2 \\ \sf\blue a \blue= \blue 2 \blue2$
