How many solutions are there for these equations x minus 3y equals negative 3 negative 2y plus 6 equals 12?
with two equations, I like to line them up vertically.
x - 3y = -3
-2y + 6 =12
Well, this can only have one solution. First, subract 6 from both sides of the second equation. you now have -2y = 6. So, y = -2.
Plug that value into the first equation: x - (-2 * 3) = -3. You will get x - (-6) = -3. add negative six (or subract six, whichever way you like to look at it) from both sides. you get -9.
so, x= -9 and y = -2.
there is no other real solution to this problem, so there is only one answer to it.
