Answer: Because the y terms cancel
Step-by-step explanation:
Hi, this approach is called the addition method.
By adding both equations we can cancel one term that contains one variable, and calculate the remaining variable.
For example, in this case:
8x + 3y = 27
+
4x-3y = 9
_______
12x = 36
Now, we can solve for x:
x = 36/12
x = 3
Now, simple replace the value of x in any equation to obtain the value of y:
4x-3y = 9
4(3)-3y =9
12-3y =9
12-9 = 3y
3 =3y
3/3 =y
y=1
Answer:
im not sure if this is rite
Step-by-step explanation:
jason=a+22
ann=a
a+22+4=2a+4
a+26=2a+4
a=22
Please lord thank you lord lord please thank you lord
The possible combination are
2=1+1
3=1+2; 2+1
4=1+3; 2+2; 3+1
So the probability is 6/36=1/6
Hope this helped!
