Here is a similar problem that you can use to try the posted one.
Ten less than the product of a number and seven IS -50.
Let x be the number.
The product of that number and seven is represented by the expression 7x.
Ten less than that product would be:
7x - 10
And that value IS (means equals) -50:
7x - 10 = -50.
The quotient of a number and 7 (for example) can be represented by x / 7. Take it from there for your posted problem.
