Solve for x.
Assume the equation has a solution for x
-px+r = -8x-2

Graphical form: -px%2Br=-8%2Ax-2 simplifies to -px%2Br%2B8%2Ax%2B2=0

Text form: -px+r=-8*x-2 simplifies to -px+r+8*x+2=0

Cartoon (animation) form: simplify_cartoon%28+-px%2Br=-8%2Ax-2+%29

For tutors: simplify_cartoon( -px+r=-8*x-2 )

DETAILED EXPLANATION

Look at -px%2Br=highlight_red%28+-8%2Ax-2+%29.

Moved these terms to the left highlight_green%28+8%2Ax+%29,highlight_green%28+2+%29

It becomes -px%2Br%2Bhighlight_green%28+8%2Ax+%29%2Bhighlight_green%28+2+%29=0.

Result: -px%2Br%2B8%2Ax%2B2=0

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
