If a + b = 6, what is the value of 3a + 3b?

2a+b=2a+b. Without a value for a and b, the expression has no value.

The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.

That depends what either the value of a or the value of b is.

Depends on what the value of B is. It can be written as b+3

b + b + b + 7 = 223b + 7 = 223b = 15b = 5

Not by itself. If you said a+++b, then that would mean to add the incremented value of b to a and generate a result, but +++b is not valid.

That depends on the value of the variables (A, B, and C). It can be anything.

It is impossible to give any decimal/numeric value if we are not given the values of at least one variable, so the answer is B + B + B + C + C + C.

a = 15.

If a + b + c + d + 80 + 90 = 100, then a + b + c + d = -70.

10 is the value of b that would make X plus bx-24 factorisable.

If you mean: 7+2b = 1 then the value of b is -3

That depends what the value of a and b are.

If: y = x+b then y-x = b

The value of a + b depends on the values of the individual variables.The expression a + b cannot be simplified.

3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4

any number

A=8 B=4 C=14 Yes, I know I'm a genius. Mak - the all knowing one. MWAHAHAH!
