Answer: All real numbers (choice A)
We can replace x with any real number we want without worrying about restrictions. There won't be any issues such as dividing by zero or applying the square root to a negative number.
Answer:
(x,y) = (3, 1/2)
Step-by-step explanation:
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations..
To solve this, add the equations;
x + 2x + 2y - 2y = 4 + 5
3x = 9
x = 3
substitute the value of x into the first equation,
3 + 2y = 4
2y = 4 -3
2y = 1
y = 1/2
Answer:
x=-11
Step-by-step explanation:
12-4(x+2)=48
Subtract 12 from each side
12-12-4(x+2)=48-12
-4(x+2)=36
Divide by -4
-4(x+2)/-4=36/-4
x+2 = -9
Subtract 2
x+2-2 = -9-2
x=-11
