Q. Solve for

x

.

\newline

7x < 7.31 + 8.7x

\newline

Write your answer with

x

first, followed by an inequality symbol.

\newline

______

Isolate variable $x$ : Isolate the variable $x$ on one side of the inequality. $7x < 7.31 + 8.7x$ $7x - 8.7x < 7.31$ $-1.7x < 7.31$
Divide and flip inequality: Divide both sides by $-1.7$ to solve for $x$ , remembering to flip the inequality sign because we are dividing by a negative number. $\newline$ $-1.7x / -1.7 > 7.31 / -1.7$ $\newline$ $x > -4.3$
