Solve multi-step linear equations, including equations requiring simplification first.

Write and solve a multi-step equation from a representation

Problem

A level balance has \(\text{two}~\text{groups}\) on the same left side: the first contains \(2~x\text{-}\text{tiles}\) and \(3~\text{unit}~\text{weights}\), and the second contains \(\text{one}~x\text{-}\text{tile}\) and \(5~\text{unit}~\text{weights}\). The right side has \(20~\text{unit}~\text{weights}\). Write the represented equation, simplify it, and solve for \(x\).

Level balance with two outlined groups on the same left tray. The first has two x-tiles and three units; the second has one x-tile and five units. The right tray has twenty units. Open full size
