Answer:

(10, -20).

Explanation:

y= -5x + 30

x = 10

Substitute x = 10 in the first equation:

y = -5*10 + 30

y = -50 + 30

y = -20.

So the solution is (10, -20).

Answer: (10,-20)

Explanation:

The given system of equations :-


y= -5x + 30------------(1)\\\\x= 10----------------(2)

To solve the above system , we substitute the value of x= 10 in equation (1), we get


y= -5(10) + 30

Simplify ,


y= -50+ 30\\\\\Rightarrow\ =-20 (3)

Therefore from (2) and (3) , we get

The solution to the given system of equations : (x,y) = (10,-20)
