Answer:
Option A) x = 3 and y = 5
Step-by-step explanation:
−7x + 3y = −6_____ first equation
−3x + 3y = 6_____ second equation
Since both equations have "y" that share the same coefficients (that is 3),we can solve this equation.
---First step is to subtract the equation 2 from 1
−7x + 3y = −6
−3x + 3y = 6
From the above equation, we have
-4x = -12
Divide both sides by -4
X = 3
--- Substitute x = 3 in equation 1
−7x + 3y = −6
-7(3) + 3y = -6
-21 + 3y = -6
3y = 21 - 6
3y = 15
Y = 5
X = 3 and y = 5( option a)
