Question

2x-3/4y=-7:x+1/2y=0
elimination, at least x or y solved.

Answer 1

Is that (3/4)*y and (1/2)*x or 3/(4y) and 1/(2x)?

Answer 2

uh. 3/4. *y. and 1/2y. 1/2 is just y.

Answer 3

?

Answer 4

@Fireflame13 Think on this a little. Printing in a book is not the same as writing in a line. You MUST remember your Order of Operations. Use parentheses to enforce it where it is ambiguous or difficult.

(1/2)y = \(\dfrac{1}{2}y\) and is unambiguous and not confusing.

1/(2y) = \(\dfrac{1}{2y}\), and is pretty clear.

1/2y = \(\dfrac{1}{2}y\), but we really can't tell if you MEANT to write that and many will be confused by it.

Answer 5

ok...

Answer 6

Now to the problem...

2x-(3/4)y=-7
x+(1/2)y=0

Multiply the second equation by -2 and see if anything presents itself.

Answer 7

-2x-1=0

Answer 8

ok.

Answer 9

gosh!!!!

Answer 10

Did you add the equations? Something magic may occur.
