If b = 5 then 15-10 = 5
if you meant to write the problem as "3b + 5 = 29", then this is how to solve: 3b + 5 = 29 - 5 - 5 subtract 5 from each side 3b = 24 simplify b = 8 divide each side by 3 to get b by itself
It is an equation and the value of b is 3
b is the square root of 5/3
Probably b.
If b = 5 then 15-10 = 5
(3b)5 = 243 b5The actual numerical value depends on the value of ' b ',and it changes instantly any time ' b ' changes.
If a + b = 6, what is the value of 3a + 3b?
3b2 + b - 10 = 0 This quadratic equation can be factored. (3b -5)(b +2) = 0 The equation can be solved when either (3b - 5) = 0, or (b + 2) = 0. If 3b - 5 = 0 then 3b = 5 : b = 5/3 If b + 2 = 0 then b = -2 The roots or solutions to this equation are b = 5/3 and b = -2

3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4
b is the square root of 5/3
Probably b.
let A = first card and let B = second card; then A = 3B and B = A-6; since A = 3B then B = (3B) - 6; solve B = 3 and A = 9
The equation cannot be solved as there are two unknowns. However it can be simplified and the two unknowns (a and b) expressed in terms of the second unknown. 1) Expressing a in terms of b 4a + 2 = 3b - 5 4a = 3b -7 if desired this could be stated as a = (3b - 7)/4 2) Expressing b in terms of a 3b - 5 = 4a + 2 3b = 4a + 7 if desired this could be stated as b = (4a + 7)/3
