Question

3x - 7y = -14
x=2y-3

Which equation is substituted correctly?

2y - 3 = 0

3x - 7(2y-3) = -14

3(2y-3) = -14

3(2y-3) - 7y = -14

Answer 1

Feel like there's something missing from this question

Answer 2

Same

Answer 3

that's what i was thinking

Answer 4

x=2y-3

Answer 5

i forgot that part at the top

Answer 6

Does it give you any other equation?

Answer 7

3x - 7y = -14

Answer 8

Yeeeaaaaahhhh
Should have probably included that too xD

So we have a x= 2y-3
And we have that equation

So you can substitute one into the other

Here's an example so you can see how

a = 3b
2a + 2b = 4

Because our first equation is a = 3b
That means since they're equal that they're interchangable

so you go from

2a + 2b = 4

To

2(3b) + 2b = 4

Answer 9

Does that make sense?
