Solve for b in the following formula: A=1/2(a+b)
To solve for b, you can start by multiplying both sides of the equation by 2 to eliminate the fraction:
2A = a + b
Then, subtract a from both sides:
2A - a = b
Therefore, the value of b is given by the equation b = 2A - a.
To solve for b in the equation A = 1/2(a + b), we need to isolate the variable b on one side of the equation.
1. Multiply both sides of the equation by 2 to eliminate the fraction:
2A = a + b
2. Subtract a from both sides to isolate the variable b:
2A - a = b
So, the value of b is equal to 2A - a.
