Question

Solve equation for x. Provide the justifications for each step. See the first example as a reminder for the types of justifications that might be used.

Answer 1

We have the next equation

$-16=3x+11$

Justification

Subtraction property of equality

$\begin{gathered} -16-3x=3x-3x+11 \\ -16-3x=11 \end{gathered}$

Justification

Addition property of equality

$\begin{gathered} -16+16-3x=11+16 \\ -3x=27 \end{gathered}$

Justification

Division property of equality

$\begin{gathered} \frac{-3}{-3}x=\frac{27}{-3} \\ x=-9 \end{gathered}$

ANSWER

x=-9
