I need help on these three questions BEFORE 10:00 PM. Please someone show me how to do them step by step!
Solve the equation for y in terms of x
then find the solutions of the equation for the given values of x.
1.x + y = 1 [values of x: 3, 1, 2]
2.x+ 4y = 20 [values of x: 4, 8, 0]
3.x  2y= 8 [values of x: 6, 2, 10]
Thanks a MILLION!!

i don't know if i did this correct but this is whut i got for number 1
x + y = 1 [values of x: 3, 1, 2]
3+y= 1
for the value of 3 y=4
value of 1 y=2
