I'm sorry I can't show you, but LaTex doesn't allow you to show short division.
You can find out how to do it here, on Wikipedia's page. https://www.wikiwand.com/en/Short_division

Make x the subject of these equations.

shepuryov [24]

$(1)a(x + b) = c \\ ax + ab = c \\ ax = c - ab \\ \frac{ax}{a } = \frac{c - ab}{a} \\ x = \frac{c - ab}{a}$

$(2)8(x + a) = b \\ 8x + 8a = b \\ 8x = b - 8a \\ \frac{8x}{8} = \frac{b - 8a}{8} \\ x = \frac{b - 8a}{8}$

$(3)a(x - 7) = b \\ ax - 7a = b \\ ax = b + 7a \\ \frac{ax}{a} = \frac{b + 7a}{a} \\ x = \frac{b + 7a}{a}$

$(4)c(2 + x) = 6 \\ 2c + cx = 6 \\ cx = 6 - 2c \\ \frac{cx}{c} = \frac{6 - 2c}{c} \\ x = \frac{6 - 2c}{c}$
