Which expression can be substituted for x in the top equation of the system below to solve the system by substitution?
2x + 10y = 1
x – 4y = –4
1. 4y – 1
2. y – 4
3. 4y – 4
4. 4 – 4y
I need some help with substition, here is a problem.. can you help me work through it. Please don't give me the answer, just tell me what I have to do. I tried putting them all into the equation, but the answers I get are not logical, I am so confused!
