If: -x-3y = -4 and 3x+5y = 16
Then: x = 7 and y = -1
x = 7, y = -1
4
40
7
It is: 32.35 minus 10.63 equals 21.72
x = 4 and y = 7 which will satisfy both equations
16
The solutions are: x = -2 and y = 4
4
{-1,-2}
Add the two equations together. This will give you a single equation in one variable. Solve this - it should give you two solutions. Then replace the corresponding variable for each of the solutions in any of the original equations.

You can write this as two equations, and solve them separately. The two equations are:x - 19 = -3and:-x - 19 = -3
find the common multiple of 4 and 480 then minus 4. Answer is 1 over 3 and N squared. Your welcome i am your saviour.
