Solve for: (0.4x+1.8) * 0.15=6

Expression: $\left( 0.4x+1.8 \right) \times 0.15=6$

Distribute $0.15$ through the parentheses

$0.06x+0.27=6$

Move the constant to the right-hand side and change its sign

$0.06x=6-0.27$

Subtract the numbers

$0.06x=5.73$

Divide both sides of the equation by $0.06$

$\begin{align*}&x=95.5 \\&\begin{array} { l }x=\frac{ 191 }{ 2 },& x=95 \frac{ 1 }{ 2 }\end{array}\end{align*}$
