Urgent- Silmutanous Equations help.

Hi.
I really need help on Simultaneous Equations. I have an exam on Wednesday as part of my Access to Law course. I don't know where else to get help. I have the questions to answer as part of revision but I just can't understand them. Can someone help me. I don't have any friends or family who would understand. If I fail this exam I am of the course and lose my uni place( and any chance of getting freedom from how my parents treat me.)

Try using BBC bitesize but ill try my best to explain.

You have two methods, elimination and substitution. With substituation, you rearrange one of the equations in the form of y= or x=. You then sunstitute the rearranged form into a second equatiom to find x or y depending on the form you rearranged to. Whatever values you find, you sub into an equation to fimd the values of the othrr variable. Check in the alternate equation to see if your vlues are correct. I will send images with examples to make understanding more easier
