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

B is the answer B=(10,-20)

Answer 2

Given the system of equations: y = -5x + 30 x = 10 To solve the equation, since the second equation in the system gives the value of x, we substitute the value of x to the first equation, to get: y = -5(10) + 30 = -50 + 30 = -20 Therefore, the solution to the system is x = 10 and y = -20 which is written as (10, -20)
