$$8x\cdot4\cdot\frac{990}{248} = 8x\cdot4\cdot\frac{990}{248}$$
Answer
The equation has an infinite number of solutions.
Explanation
$$ \begin{aligned} 8x\cdot4\cdot\frac{990}{248} &= 8x\cdot4\cdot\frac{990}{248}&& \text{multiply ALL terms by } \color{blue}{ 248 }. \\[1 em]2488x\cdot4\cdot\frac{990}{248} &= 2488x\cdot4\cdot\frac{990}{248}&& \text{cancel out the denominators} \\[1 em]31680x &= 31680x&& \text{move the $ \color{blue}{ 31680x } $ to the left side} \\[1 em]31680x-31680x &= 0&& \text{simplify left side} \\[1 em]31680x-31680x &= 0&& \\[1 em]0 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{blue}{ 0 = 0 } $ is TRUE for any value of $ x $, we conclude that the equation has infinitely many solutions.
