See the attached picture.
The domain is the input and the ramge is the output.
Domain = x Range = y
You cant say that the domain/range is ALL NUMBERS you can only say it is and x/y value.
Input = x. Output = y
<span>3x = y + 7
</span><span> y =3x-7
</span>
<span>8x = 2y + 5
</span><span>8x = 2(3x-7) + 5
8x=6x-14+5
8x-6x=-9
2x=-9
x=-4.5
</span><span>8x = 2y + 5
</span>8(4.5)=2y+5
36=2y+5
2y=31
y=15.5
