Please show all work and thought process alongside. I$\text{'}$m very confused and do not know where to start or what steps proceed. G$-4.$ Consider the chemical reaction described by the equation

$C{H}_4(g)+H_{2}O(g)CO(g)+3H_2(g)$

at $300K.$ If $1\mathrm{.}00$atm of $C{H}_4(g)$ and $H_{2}O(g)$ are introduced into a reaction vessel, the

pressures at equilibrium obey the equation

$\frac{P_{CO}{P}_{H_2}^3}{P_{C{H}_4}{P}_{H_{2}O}}=\frac{(x)(3x{)}^3}{(1-x)(1-x)}=26$

Solve this equation for $x.$
