Sherry uses the steps below to solve the equation x+ (-8) = 3x+6

step 1

step 2

step 3

step 4

add 1 negative x-tile to both sides and create zero pairs

add 8 positive unit tiles to both sides and create zero pairs.

divide the 14 unit tiles evenly among the 2 x-tiles

the solution is x= 7

what is sherry's error?

See explanation

Step-by-step explanation:

Sherry has the equation

1 step: Add 1 negative x-tile to both sides and create zero pairs:

2 step: Add 8 positive unit tiles to both sides and create zero pairs:

3 step: Add 14 negative unit tiles to both sides and create zero pairs:

4 step: Divide the 14 negatuve unit tiles evenly among the 2 x-tiles:

5 step: The solution is

Or Sherry can combine step 2 and 3 and having the equation add 6 negative unit tiles to both sides and create zero products:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
