Question

1) x = 5, y = 4 is a solution of the linear equation: *

a)2x + y = 17

b)x + y = 17

c)x + 2y = 13

d)3x – 2y = 17

​

Answer 1

Answer:

I am first so I don't know please ask something I know

Answer 2

Answer:

c).x + 2y = 13

Step-by-step explanation:

substitute x = 5 and y = 4 in all options,

a). 2(5) + 4 = 17⇒ 10 + 4 =17⇒ 14 ≠ 17

b). 5 + 4 = 17⇒9 ≠ 17

c). x + 2y = 13⇒ 5 + 2(4) = 13⇒ 5 + 8 = 13⇒ 13 = 13

d). 3(5) - 2(4) = 17⇒ 15 - 8 = 17⇒ 7 ≠ 17
