too easy!.. hehe
first you have to isolate y on the left side to do that remove -7.
observe the steps below
y - 7 > -12
y - 7 + 7 > -12 + 7 Addition Property of Equality
y - 0 > -5 Closure Property of Equality
y > -5
D: {-4, -3, -2, -1, 0 ,1, 2, 3... }

y - 7 > -12
y > - 12 - (-) 7
That means
y > - 12 + 7
y > - 5

y-7>-12
y > -12+7
y > -5
y+5>0
y = -5
i'm not sure if the last two steps are correct

to solve this problem you have to make the > to =.
then you will have y-7=-12
then y= - 5
then now you change back.
y>-5

Just take the -7 across, change the sign and add.
