Answer:
x= -1 and y= 0
Explanation:
These are two simultaneous equations
this is equation 1
this is equation 2
We can use equation 1 as it is in terms of x and put it in equation 2 which means
becomes
now we know the value of x and to find out the value of y we put the value of x in any equation either number 1 or 2
lets take equation 1
So this is how you solve your equations algebraically
