If: a = 2b+c

Then: a-c = 2b

And: b = (a-c)/2

This is the same as: 13-2b = 21 -2b = 21-13 -2b = 8 b = -4

8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3

3a + 2b = c (find a in terms of b and c)3a +2b -2b = c - 2b3a = c - 2b3a/3 = (c - 2b)/3a = (c - 2b)/3In order to find the value of a, you can give any values to b, and c (except a zero value).

-b+5b-2b=2b

2(a+b) is 2a plus 2b in factored form.

a = 2b + c then a - 2b = c ie c = a - 2b

c= a-2b

a-2b=c

b= 1/2 (a - c)

c= (a+d) / 2b

=2b

(a+d)/2b=c

If a=2bc+db= (a - d) / 2c If a=2b+c b=1/2(a-c)

a + 2b = c a = c - 2b

To find the solution to this equation, you need to rearrange the terms and solve for the variable. 4 = 2b + b^2 can be rewritten as b^2 + 2b - 4 = 0. You can then solve this quadratic equation by factoring, completing the square, or using the quadratic formula.

A = 2b + cSubtract 'c' from each side:A - c = 2bDivide each side by 2:b = 1/2 (A - c)
