Question

Whats the solution set of the following equation -8×+×+15=-7×+12

Answer 1

Given data:

The given equation is -8x+x+15=-7x+12.

The given equation can be written as,

$\begin{gathered} -8x+x+15=-7x+12 \\ -7x+15=-7x+12 \\ 15=12 \end{gathered}$

The above expression is false.

Thus, there is no value of x, so the answer is ϕ.
