Step 1
: Group the like terms together, which are the terms containing the same variable(s).

\begin{align*}
1 + 3x - 8x + 7 &= \boxed{(1 + 7)} + \boxed{(3x - 8x)} \ &= 8 + (- 5x) \end{align*}

Step 2
: Now, simplify the expression in each box separately.

\begin{align*}
For the first box, we have: \boxed{(1 + 7)} &= 1 + 7 \ &= 8 \end{align*}

Final Answer

The simplified expression is $8 - 5x$.
