First, distribute $0.9$ across $(5x + 15)$ to get $4.5x + 13.5$. Then, distribute $-1$ across $(x + 3)$ to get $-x - 3$. Setting up the equation gives $4.5x + 13.5 = 2.3 - x - 3$. Simplifying, we combine like terms and solve for $x$, which results in $x = - \frac { 142 } { 55 }$.

Solve - 0.9(5x+15)=2.3−(x+3)0.9 ( 5 x + 15 ) = 2.3 - ( x + 3 )0.9(5x+15)=2.3−(x+3)

Solve
- $0.9 ( 5 x + 15 ) = 2.3 - ( x + 3 )$
