Answer:
y=-3-3x
Step-by-step explanation:
Transpose the equation for y
y=-12/4-12x/4
y=-3-3x
There is only one solution and the solution is x=-22
Answer:
x=2 and y= 4
Step-by-step explanation:
y = x +2 ----------(i)
y = 3x -2--------(ii)
Now, comparing (i) and (ii)
x+2= 3x-2
=>x-3x = -2-2
=>-2x= -4
=>2x= 4
=>x= 2
From eq (i)
y= x+2 = 2+2= 4
I believe your answer is C
