Solve this simultaneous equation by elimination:
x+y = -4
x-y = 2
Add both equations together:
2x = -2
Divide both sides by 2 to find the value of x:
x = -1
Substitute the value of x into the original equations to find the value of y:
Therefore: x = -1 and y = -3
Remember that a - - is equal to a +
So -1- -3 = 2
