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} (-3)/(-3)x=(27)/(-3) \\ x=-9 \end{gathered}`

ANSWER

x=-9
