The other equation could be
2y - 6x = -6
Solving:-
y - 3x = -3..........(1)
2y - 6x = -6........(2)
multiplyng the first equation by 2 gives
2y - 6x = -6
so equations (1) and (2) are the same equation
If we graph them they will be the same line
Every point on that line will be a solution.
So there are infinitely many solutions
Dan takes about 8 minutes to run a mile
Yoko payed around $1.75
To solve this, add 17 to both sides:
x = -25 + 17
x = -8
No.5=1/3x=21
So x is twenty one21
I'm assuming its asking what time he finished? I added it up and it seems to be 7:42 pm.
