Answer: x =-7 and y =10
Step-by-step explanation:
The given system of equations :
Add equation (1) and (2), we get
Put value of x in (2), we get
hence, the solution of the given system is x =-7 and y =10.
Answer: 18x -15 -y =0
Step-by-step explanation:
because linear equations in two variables are always in the format of ax+by+c=0
where a,b and c are constant terms
in this case a = 18; ax= 18x
b= -1 , by= -y
c= 15
The sum is 34 and the add and multiemployer
