What is algebra?

What is an equation? How it is different from an inequality?

Using literals, write the following in algebraic forms:

 $3$ times $y$ to which $13$ is added

Using literals, write "$5$ times $y$ from which $8$ is subtracted" in algebraic form.

Using literals, write the following in algebraic forms:

 $y$ multiplied by $-3$ then $7$ is added to the result 

Using literals, write the following in algebraic forms:

 $y$ multiplied by $-5$ and the result is subtracted from $10$

Pick the solution from the values given in the bracket next to the equation . Show that the other values do not satisfy the equation.
