PLEASE HELP math review ...?

can someone help me factor this ,
Question # 1:
Your kitchen has a 30 m ^2 of floor space availiable for pizza ovens and refrigerators, and you want to use all of it. Each refrigerator takes up 3 m ^2 of floor space, and each oven requires 2 m^2 of space.
Let x represent the number of refrigerators and y the number of pizza ovens. Write and equasion representing the information given above.

2.Another factor to consider is the utility bill you will have to pay, your buget is 210$ per month. The manufacturer of the appliances you will use has told you that each refrigerator will cost $10per month to operate and each pizza oven will cost 25$ per month. Using the same variables as question 1, write an equation representing the utility cost information.

For the first one, since you want to use ALL of the available space for the pizza ovens and refrigerators, the equation should be

3x + 2y = 30

For the second one, since your budget is $210, it means your bill cannot exceed that amount each month but it could be less, so that would be an inequality

10x + 25y <= 210
