9-91.

Solve these equations for $x$.

1. $2(x + 3.5) = 16$

Distribute the $2$.

$x = 4.5$

1. $23 + 5x = 7 + 2.5x$

Move all variables to one side of the equation and all constants to the other side of the equation.

1. $3x+4.4=-(6.6+x)$

Remember to distribute the negative sign to the terms inside the parentheses.
$3x+4.4=-6.6-x$

Add $x$ to both sides and subtract $4.4$ from both sides to isolate $x$.
$4x=-11$

$x=-2.75$
