I have never been great at algebra.
Thank you for the opportunity to help you with your question! Hope your day is going well!
Hello, the goal is to solve for y.
1. 2x4y=1 (let's divide the whole equation by 2)
x2y=1 (subtract x from both sides)
2y=x+1 (divide by 2 to both sides)
y=x/21/2
Try substituting in different x's to find it's y valus.
x  y 
1  0 
2  1/2 
3  1 
4  3/2 
5  2 
6  5/2 
So some points are ....(1,0),(2,1/2),(3,1),(4,3/2),(5,2),(6,5/2)....
2. 5+10y=5 (let's divide the whole equation by 5)
1+10y=1 (add one to both sides)
10y=0 (divide by 10 to both sides)
y=0
Thus this is a horizontal line (it crosses the y axis, and gives all the points of the x axis).
so some points are ...., (1,0)(0,0),(1,0),(2,0)....
I realized I did the wrong things for these problems, because you are supposed to use the substitution method. I will fix it, and give the correct way to do the answer.
Solve for y using the second equation
5+10y=5 (add five to both sides)
10y=0
y=0
Substitute y=0 into the first equation
2x4(0)=2
2x0=2
2x=2
x=1
Therefore your answer is x=1, and y=0
