Solve 2x−10x=72 for x.

Answer 1

To solve the equation \(2x - 10x = 72\), start by combining like terms on the left side:

\[ 2x - 10x = -8x \]

So the equation now looks like:

\[ -8x = 72 \]

Next, divide both sides by -8 to isolate \(x\):

\[ x = \frac{72}{-8} \]

Simplifying this gives:

\[ x = -9 \]

Thus, the solution is:

\[ \boxed{-9} \]
