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
