To solve for b, we can start by isolating b on one side of the equation.
4a = 2b - 7
First, let's move the -7 to the other side of the equation by adding 7 to both sides:
4a + 7 = 2b
Next, divide both sides of the equation by 2 to solve for b:
(4a + 7)/2 = b
Now, we can substitute a = 3 into the equation to find the value of b:
(4(3) + 7)/2 = b
(12 + 7)/2 = b
19/2 = b
Therefore, when a = 3, the value of b is 19/2 or nine-halves.
Solve for b, then find the value of b when a = 3. 4a = 2b − 7 (1 point) Responses – – Image with alt text: nine-halves Image with alt text: five-halves Image with alt text: nineteen-halves 17
