Answer:
The answer to your question is (3, 0)
Step-by-step explanation:
Data
4x + 2y = 12 Equation l
x - y = 3 Equation ll
Process
To solve this problem use the elimination method
1.- Multiply equation ll by 2
4x + 2y = 12
2x - 2y = 6
6x 0 = 18
2.- Solve for x
6x = 18
x = 18/6
x = 3
3.- Substitute x in equation ll to find y
3 - y = 3
-Solve for y
-y = 3 - 3
y = 0
4.- Write the solution
(3, 0)
X=-3 because first substitute the value of y into the original equation -2x-3=x+6 then isolate the variables -2x-x=6+3 which is -3x=9 then we can divide x=9/-3 which =-3
