3x + 5y = 78

2x - y = 0

The point of intersection of the lines has an x-coordinate of ___.
@salehgeek

Answer 1

you can rewrite the second equation as \(2x=y\) and then replace the \(y\) in the first equation by \(2x\)

Answer 2

x=6 and y= 12

Answer 3

to get \(3x+5(2x)=78\) and then solve for \(x\)

Answer 4

@brittnicoleee_ do you have the answer you are looking for?

Answer 5

yes
x + 5y = -2

2x + y = 5

The point of intersection of the lines has a y-coordinate of ___.

Answer 6

If not I can help.

Answer 7

Ok just making sure.

Answer 8

x + 5y = -2

2x + y = 5

The point of intersection of the lines has a y-coordinate of ___.
