. Now, putting those two together for the system of equations, it's easiest to add them. The result will be
which when simplified gives you the value of x. Taking the value of x, you can substitute in the second equation to find the value of y.

Answer:
a. 4
b. -8
c. -2
Step-by-step explanation:
Take any number x;
Its opposite is -x
The opposite of its opposite is x
Using the above statements, we can solve the following questions
Solving (a): -4
In this case:
The opposite; -x is
Solving (b): 8
In this case:
The opposite; -x is
Solving (c): -2
In this case:
The opposite; -x is
The opposite; -(-x) is
So we start by combining like terms;
Now we have;
We then subtract 1 from both sides;
Then we divide both sides by 5;
Leaving the final answer to be h = -2
