Question

For the following system, subtract the second equation from the first equation.
3x - 4y = 7
3x + 2y = - 5
What is the resulting equation in simplest form?

Answer 1

1. -6y = -12
2. -6y = 12
3. -2y = -12
4. 2y = 12

Answer 2

did you subtract the second equation from the first?

Answer 3

no, how do i do that?

Answer 4

subtract term by term.... start with the 3x - 3x, then -4y - 2y, then 7 - -5

Answer 5

0 (-6y) (12)

Answer 6

there's an equal sign between the y and the 12...

Answer 7

so the answer would be -6y = 12?

Answer 8

yep
