Answer: b= 6-a/2
Explanation:
Always try to isolate what you are looking for.
a+ 2b=12 (subtract a)
2b= 12-a (divide by 2 to isolate b)
b= 12-a/2 (divide both numbers by 2 to get the smallest fraction)
b= 6-a/2 [b is now isolated :) ]
Answer:
Add '-2b' to each side of the equation.
a + 2b + -2b = 12 + -2b
Combine like terms: 2b + -2b = 0
a + 0 = 12 + -2b
a = 12 + -2b
