−2x+8=

−x+7

1 answer

To solve the equation \(-2x + 8 = -x + 7\), we can follow these steps:

  1. Add \(x\) to both sides to eliminate \(-x\) from the right side:

\[ -2x + 8 + x = -x + 7 + x \]

This simplifies to:

\[ -2x + x + 8 = 7 \]

So we have:

\[ -x + 8 = 7 \]

  1. Subtract 8 from both sides to isolate the term with \(x\):

\[ -x + 8 - 8 = 7 - 8 \]

This simplifies to:

\[ -x = -1 \]

  1. Multiply both sides by -1 to solve for \(x\):

\[ x = 1 \]

Thus, the solution to the equation is \(\boxed{1}\).

To verify, we can substitute \(x = 1\) into the original equation:

Left side: \[ -2(1) + 8 = -2 + 8 = 6 \]

Right side: \[ -(1) + 7 = -1 + 7 = 6 \]

Both sides are equal, confirming that \(x = 1\) is correct.
