Answer:

c. step three

Step-by-step explanation:

CORRECT WAY

step one: -7/ -2 / 4/9 (flip 4/9)

step two: -7/-2 * 9/4 (simplify)

step three: = 63/8

Step three is incorrect because it's not - it's positive.

She forgot that a negative divided by a negative is a positive.

So -7/-2 is the same as 7/2

Hope this helps ya!!!

Solve the following system of equations by elimination​
olya-2409 [2.1K]

Answer:

y = -6

x = 1

Step-by-step explanation:

-x + 2y = -13

-x - 2y = 11

Sum the equations:

-x -x = -2x

+2y - 2y = 0

-13 + 11 = -2

then

-2x = -2

x = -2/-2

x = 1

from the first eq.

-x + 2y = -13

-1 + 2y = -13

2y = -13 + 1

2y = -12

y = -12/2

y = -6

check:

from the second eq.

-x -2y = 11

-1 -(2*-6) = 11

-1 -(-12) = 11

-1 + 12 = 11
