Question

Y = –5x + 30

x = 10
What is the solution to the system of equations?

(–20, 10)
(10, –20)
(10, 4)
(4, 10

Answer 1

The second statement is correct.

Answer 2

The correct option is 2.

Explanation:

The given system of equations is

`y=-5x+30` .... (1)

`x=10` ..... (2)

Substitute the value of x from equation (2), in equation (1).

`y=-5(10)+30`

On simplification, we get

`y=-50+30`

`y=-20`

The value of xis 10 and the value of y is -20. So, the solution of the given system of equation is (10,-20).

Therefore the correct option is 2.
