X = independent variable
Y = dependent variable

1. y = 5x + 10   
  20 = 5x + 10   plug in
 -10         - 10    subtract like terms since 10 is positive
10/5= 5x/5         divide by 5, trying to get x by itself
    2 = x              5 divided by 5 cancels out and 10 divided by 5 is 2


y = 5(30) + 10
y = 150 + 10
y = 160
