Question

-16+2x=4x-(16+12)

Answer 1

\[x=6\]

This is because;
\[-16+2x=4x-(16+12)\]
When there is a negative/minus sign before a parentheses you just add a 1 behind it.
\[-16+2x=4x-1(16+12)\]
Now, use distributive property to take parenthesis away;
\[-1*16=-16\]\[-1*12=-12\]Which turns the original equation into;
\[-16+2x=4x-16-12\]Combining like terms you get;
\[-16+2x=4x-28\]
Next, subtract 2x from both sides.
\[-16+2x-2x=4x-28-2x\]
Which leaves;
\[-16=2x-28\]
Next you add 28 to both sides.
\[-16+28=2x-28+28\]
\[12=2x\]
Now divide both sides by 2;
\[\frac{ 12 }{ 2 }=\frac{ 2x }{ 2 }\]
\[6=x\]
