z remains undefined.
a=24 b=16 c=18
Yes because if 1+0=1 than 0 plus b equals b
A+c= 2a+b
Because there is no way to define the divisors, the equations cannot be evaluated.
1-6b+7=14 8-6b =14 -6b =6 -b =1 b =-1
a=24 b=16 c=18
the answer is a
2a. (a, b and c are all equal.)
Yes because if 1+0=1 than 0 plus b equals b
A+c= 2a+b
If you do not assume that "plus" is commutative, all that can be said that it is equal to A plus B.
Because there is no way to define the divisors, the equations cannot be evaluated.
1-6b+7=14 8-6b =14 -6b =6 -b =1 b =-1
That factors to (a + 1)(a + b) a = -1, -b b = -a
-13
Commutative, not communtative The mathematical property of being able to change the order of the numbers and not change the answer. A plus B equals B plus A (1 plus 3 equals 4, 3 plus 1 equals 4) A times B equals B times A (2 times 5 equals 10, 5 times 2 equals 10) Addition and multiplication are commutative operators A minus B is not necessarily equal to B minus A (6 minus 4 equals 2, 4 minus 6 equals minus 2) A divided B is not necessarily equal to B divided A (9 divided by 3 equals 3, 3 divided by 9 equals one-third) Subtraction and division are not commutative operators
1 is the answer. -(-4)- 3 = 4-3 = 1 .
