Question

What value of x can you substitute into each of these expressions to give you the same answer?

x + 12
6x - 8
4x

Answer 1

Explanation:

x4

\begin{gathered}4 + 12 = 16 \\ 6 \times 4 - 8 = 16 \\ 4 \times 4 = 16\end{gathered}

4+12=16

6×4−8=16

4×4=16

Answer 2

`x = 4`

`4 + 12 = 16 \\ 6 * 4 - 8 = 16 \\ 4 * 4 = 16`
