The equation is $\"\"$ .

$\"\"$ (Multiply: $\"\"$ )

Apply Subtraction property of equality: Subtract 10 from each side

$\"\"$

$\"\"$ (Commutative property: a + b = b + a)

$\"\"$ (Additive inverse property: $\"\"$ )

$\"\"$ (Additive identity property: $\"\"$ ) $\"\"$

$\"\"$ (Evaluate power: $\"\"$ )

$\"\"$ (Add: $\"\"$ )

$\"\"$ (Divide: $\"\"$ )

Left side and right side are equals. $\"\"$

The solution is "set of all real numbers".
