Question

$$3+2|x+5|=7$$

Answer

x=-7,-3

Solution


Subtract \(3\) from both sides.
\[2|x+5|=7-3\]
Simplify  \(7-3\)  to  \(4\).
\[2|x+5|=4\]
Divide both sides by \(2\).
\[|x+5|=\frac{4}{2}\]
Simplify  \(\frac{4}{2}\)  to  \(2\).
\[|x+5|=2\]
Break down the problem into these 2 equations.
\[x+5=2\]
\[-(x+5)=2\]
Solve the 1st equation: \(x+5=2\).
\[x=-3\]
Solve the 2nd equation: \(-(x+5)=2\).
\[x=-7\]
Collect all solutions.
\[x=-7,-3\]
