A financial analyst is using the substitution method to solve a system of equations representing two different investment accounts. What is the primary action taken during the 'Solve' step of this method?

A project coordinator is calculating the costs of two different service contracts. To find the individual costs using a system of equations, arrange the following steps of the standard problem-solving strategy in the correct order.

A financial analyst is translating verbal audit reports into a system of linear equations to compare two account balances, $n$ and $m$. Match each verbal description from the reports to its correct algebraic translation.

A warehouse supervisor is monitoring the inventory of two items, Item A ($x$) and Item B ($y$). The combined inventory of both items is 200 units, represented by the equation $x + y = 200$. The supervisor also knows that Item A has 30 units fewer than Item B, represented by the equation $x = y - 30$. To solve this system of equations using the substitution method, the supervisor replaces the variable $x$ in the first equation with the expression _______.

A logistics manager is comparing the shipping costs of two different carriers ($x$ and $y$). According to the seven-step problem-solving strategy, the manager applies the Translate step by converting a verbal constraint, such as 'Carrier X is $50 more expensive than Carrier Y,' into the algebraic equation $x = y + 50$.

A laboratory technician is using a system of equations to determine the precise concentrations of two chemical solutions. Why is the substitution method often preferred over a graphing approach when the results are expected to be non-integer values, such as 15.4% or 9/2?

A warehouse manager is using a system of equations to determine the storage capacity of two different warehouse sections. After identifying that the objective is to find the capacity of Section A and Section B, the manager assigns the variables $c_1$ and $c_2$ to represent these unknown capacities. According to the seven-step problem-solving strategy, which step is the manager performing by assigning these variables?
