$$\left(\mathrm{2}{a}+\mathrm{8}{b}+\mathrm{90}\right)−{x}=\left(−\mathrm{3}{a}+\mathrm{7}{b}+\mathrm{16}\right) \\ $$$${x}=\left(\mathrm{2}{a}+\mathrm{8}{b}+\mathrm{90}\right)−\left(−\mathrm{3}{a}+\mathrm{7}{b}+\mathrm{16}\right) \\ $$$${x}=\mathrm{2}{a}+\mathrm{8}{b}+\mathrm{90}+\mathrm{3}{a}−\mathrm{7}{b}−\mathrm{16} \\ $$$$=\mathrm{5}{a}+{b}+\mathrm{74} \\ $$
