The answer to your question is letter C
Step-by-step explanation:
Equations
x + 4y = 10
5x + 10y = 20
Process
1.- Substitute all the options in both equations and evaluate them
a) x = 3, y = 2 This option is incorrect
(3) + 4(2) = 10 3 + 8 = 10 11 ≠ 10
5(3) + 10(2) = 20 15 + 20 = 20 35 ≠ 20
b) x = 2, y = -3 This option is incorrect
(2) + 4(-3) = 10 2 -12 = 10 -10 ≠ 10
(2) + 10(-3) = 20 2 - 30 = 20 -28 ≠ 20
c) x = -2, y = 3 This is the right answer
(-2) + 4(3) = 10 -2 + 12 = 10 10 = 10
5(-2) + 10(3) = 20 -10 + 30 = 20 20 = 20
d) x = 3, y = -2 This option is incorrect
(3) + 4(-2) = 10 3 - 6 = 10 - 3 ≠ 10
5(3) + 10(-2) = 20 15 - 20 = 20 -10 ≠ 10
