So, if you’re only given the y coordinate in your problem, you would plug that back into your equation
y=5x-1 turns into
4=5x-1 and you can solve by
5=5x
1=x
so the ordered pair turns out to be
(1,4)

y=5x-1

use the substitution method since y= 4

4= 5x-1

move -1 to the other side

sign changes from -1 to +1

4+1= 5x-1+1

4+1= 5x

5= 5x

divide both sides by 5 to get x by itself

5/5= 5/5x

Cross out 5 and 5, divide by 5 and then becomes 1*1*x= x

x=5/5

Answer: x= 1
