Write an algebraic expression for the sum of a number and 8

I am not so sure but i think this might work.

Write an algebraic equation for “8 more than x is equal to 17 .” Write an algebraic inequality for “one-fifth of x is greater than x minus .” Write an algebraic inequality for “5 added to the quotient of a number and 3 is less than or equal to 7 times the sum of the number and 2.” For the number, use the variable.

Xis -1/2
y is 35/4.
