To solve for b, we need to isolate it on one side of the equation.
We can start by isolating the term with b on one side:
4a = 2b – 7
We can then add 7 to both sides of the equation to get rid of the -7:
4a + 7 = 2b
Next, we can divide both sides of the equation by 2 to solve for b:
(4a + 7) / 2 = b
Simplifying further, we have:
b = (4a + 7) / 2
To find the value of b when a = 3, we substitute a = 3 into the equation:
b = (4(3) + 7) / 2
b = (12 + 7) / 2
b = 19 / 2
b = 9.5
Therefore, when a = 3, the value of b is 9.5.
solve for b then find the value of b when a = 3. 4a = 2b − 7
