1.6y – 1.4 = 30
Also, how do I check?

y=19.625

Step-by-step explanation:

1.6y - 1.4 = 30

add 1.4 on both sides

1.6y = 31.4

divide by 1.6 on both sides to isolate y

y=19.625

to check if this is true, plug in 19.625 for y:

1.6(19.625) - 1.4 = 30

31.4 - 1.4 = 30

30 = 30

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
