Question

Given the form of the equation 3x + 2y = 3 and x – 3y = -10. Then determine the result of 3x - y !​

Answer 1

3x – y = -6

Step-by-step explanation:

To solve on the problem above, you can do it by substitution and elimination of the two equations.

3x + 2y = 3

➡️ 3x + 2.3 = 3

➡️ 3x + 6 = 3

➡️ 3x = -3

➡️ x = -1

➡️ 3x – y = 3(-1) – 3

➡️ = -3 – 3 = -6 ✅

Answer 2

-6

Step-by-step explanation:

x= -1 and y=3

3x- y

=> 3(-1)-3 = -3-3= -6
