I think you definitely need technology and objects to represent the data
8/x-7=7/2
16=7(x-7) cross multiply
16=7x-49
-7x=-49-16
-7x=-65 divides each side by -7
-7x/7=-65/7
X=65/7
Alternative form
X=92/7
Which is 1st options in your questions.
Hope this helps!
Answer of the question; -1
<span> y-4=-8(x-1) is linear
===================
</span><span>y=x4 is non linear, it is a parabola or a curved line
===================
</span><span>y-x2=4.5 is non linear as it is curved
===================
</span><span>3x + 5y = 15 is linear</span>
