Question

For each value of x, determine wether it is a solution to -11 = 1 - 2x.

Answer 1

The equation:

$-11=1-2x$

can be solve as:

$\begin{gathered} -11=1-2x \\ 2x=1+11 \\ 2x=12 \\ x=\frac{12}{2} \\ x=6 \end{gathered}$

Hence, we conclude that the solution is 6 and therefore this is the only value that satisfies this equation.
