One solution
Step-by-step explanation:
By inspection, you can see that adding either 3x or 4x to y yields the same result of 7, meaning that x must be 0. If x is 0, y must be 7, meaning that this equation has only one solution. Hope this helps!
Answer:
1716
Step-by-step explanation:
We can use nCr equation to find this
n=13
r=7
According to the formula...
P= 48/ 2x6
P=48/12
p=4
0+0=0 0+0=0+0
They are all addition, and they are all 0, and since 0 equals nothing, the sum is equivalent to 0!
