bobbie wrote y+6=15. than she wrote (y+6) divided by 3=15. Explain why the second equation is not equivalent to the first. what

irina1246 [14]

If y+6=15, then y=9. (9+6)divided by 3 would be 5, not 15.

QUICKKKK EXPERTS/ACE (and people that know it for sure comment) Brainiest Marked to the first correct answer

Olin [163]

I worked them out separately if I'm correct, then the order is:

x+5y=-2
x+5y=4 These are Inconsistent

y=3x+4
-2x+y=4 These are Consistent independent

3x+y=4
-6x-2y=-8 These are coincident

Inconsistent lines=No solution
Coincident lines=exactly on top of each other
Consistent Independant= Solution, as they cross each other.

~Hope this helps!

Simplify -3y+2x-5y-7x

Sphinxa [80]

<h3><em><u>Simplify -3y+2x-5y-7x is:</u></em></h3><h3>-8y - 5x</h3>

<em><u>Solution:</u></em>

<em><u>Given that, we have to simplify</u></em>

$-3y + 2x-5y-7x$

We can simplify the above expression by combining the like terms

Like terms are terms that has same variable ( with same exponent) with same or different coefficient

From given,

$-3y + 2x-5y-7x$

Here, like terms are -3y and -5y

And 2x and -7x

Group the like terms

$-3y-5y+2x-7x$

Combine the like terms

$-8y -5x$

Thus the given expression is simplified
