Answer:
see attachments
Step-by-step explanation:
These are "one-step" equations.
To solve the ones involving addition or subtraction, identify the constant on the same side with the variable. Add its opposite to both sides.
To solve the ones involving multiplication or division, identify the coefficient of the variable. Multiply both sides by its reciprocal (or, equivalently, divide by that coefficient).
Here are more details for the problems on the first page.
