# On the possibility of transforming a system of two equations in eight variables into the form ${A}_{7,8}={A}_{1,2}+{A}_{3,4}+{A}_{5,6}$, ${B}_{7,8}={B}_{1,2}+{B}_{3}+{B}_{5}$ with the aid of nomograms with a transparency of two degrees of freedom

## Abstract

top
This paper derives the necessary and sufficient conditions under which the system of equations ${x}_{7}=f\left({x}_{1},{x}_{2},{x}_{3},{x}_{4},{x}_{5},{x}_{6}\right),\phantom{\rule{4pt}{0ex}}{x}_{8}=g\left({x}_{1},{x}_{2},{x}_{3},{x}_{4},{x}_{5},{x}_{6}\right)$ can be transformed into the form ${A}_{7,8}={A}_{1,2}+{A}_{3,4}+{A}_{5,6},\phantom{\rule{4pt}{0ex}}{B}_{7,8}={B}_{1,2}+{B}_{3}+{B}_{5}$; this can be done with the help of nomograph with a oriented transparent.
