a=2b 4b=6c becomes 2b=3c a=3c
a + 2b = c a = c - 2b
2b=6squared, and 6x6=36

3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28
v=1/4(squareroot)a/2b make A the subject
a=2b 4b=6c becomes 2b=3c a=3c
=2b
a + 2b = c a = c - 2b

This is the same as: 13-2b = 21 -2b = 21-13 -2b = 8 b = -4
If: a = 2b+c Then: a-c = 2b And: b = (a-c)/2
2b-6=20 2b=26 b=26/2 b=13

2b=6squared, and 6x6=36
a = 2b + c then a - 2b = c ie c = a - 2b
