Answer:
x=2
Step-by-step explanation:
When solving an algebraic equation, you have to get x alone
you do this by doing the inverse of whatever is efecting x
in this case it is x+4 so you subtract 4 from x+4
x+4-4=x
but when doing something like this, you have to do the same thing to both sides
x+4<em><u>-4</u></em>=6<u><em>-4</em></u>
x=2

Answer:
A.) x-y=2 and x+2y=-2
Step-by-step explanation:
For option A, we have:
x-y=2
x+2y=-2
Subtract the first equation from the second, to get:
2y--y=-2-2
This implies that:
2y+y=-2-2
Simplify to get:
3y=-4
Divide both sides by 3 to get:

We substitute y=-1.3 into the first equation to get:
x--1.3=2
x+1.3=2
x=2-1.3
x=0.7
The solution is (0.7,-1.3), which is approximately (0.7, -1.4)
By inspection, all the other factors have solutions not close to (0.7, -1.4)
