Answer 2

3x=-12y+15
x+4y=5

x=-4y+5
x+4y=5

x+4y=5
x+4y=5

now, you tell me

Answer 3

Did you substitute?

Answer 4

@SolomonZelman
Can you finish helping me?

Answer 5

I divided eq1 by 3 and added 4y to both sides (also in eq1).

Answer 6

That gave me that these equations are same.

Answer 7

So should i put the anser is 2?

Answer 8

no

Answer 9

when you have two functions
y=f(x)
and
y=g(x)

then, the solutions are the x-values that satisfy g(x)=f(x).
If f(x)=f(x), then it is equivalent for all x values.

Answer 10

here, our f(x) and g(x) are also same. So for both y and x, we have how many solutions?

Answer 11

=we have 1 solution
