To solve for b, we need to isolate b on one side of the equation.
Starting with the equation: 4a = 2b − 7
First, let's add 7 to both sides of the equation to get rid of the -7:
4a + 7 = 2b
Next, divide both sides of the equation by 2 to solve for b:
(4a + 7) / 2 = b
Simplifying further:
2a + 7/2 = b
Now, we can substitute a = 3 into the equation to find the value of b:
b = 2(3) + 7/2
b = 6 + 7/2
b = 6 + 3.5
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 (1 point) Responses – – Image with alt text: nine-halves Image with alt text: five-halves Image with alt text: nineteen-halves 17 17
