Step 1
We have to determine whether the given problem is equation or expression. If it is an equation then we have to solve and if it is expression then simplify where problem is:
5n6n8=1712
We know that
Expression can be any numbers, variables or combination of number and variable connected through mathematical operations.
Example:
3,x2,5+17x, ...
Equation is connected through equal sign where each side should be any expression.
Example:
x=y,x2+3=0,x2+2x=7, ...
The given problem have two expressions connected through equal sign.
Hence, it is an equation.
Step 2
Now solving the equation by taking LCM of the denominator in LHS side, we get
5n6n8=1712
5n×43×n24=1712
20n3n24=1712
17n24=1712
12×17n=17×24
n=17×2412×17
=-2
Hence, solution of the equation is n=−2.
