Answer 3

To solve the equation 8x - a = 4(2x - 5) when a = -3, you need to substitute the value of 'a' into the equation and then solve for 'x'.

Step 1: Substitute 'a' with -3 in the equation: 8x - (-3) = 4(2x - 5)

Step 2: Simplify the equation: 8x + 3 = 8x - 20

Step 3: Now, we want to isolate 'x' on one side of the equation. Let's move the term with 'x' to the left side:

8x - 8x + 3 = -20

Step 4: Simplify further:

3 = -20

Step 5: There is no valid solution for 'x' since the equation simplifies to an inconsistent statement (3 = -20), which means there is no value of 'x' that satisfies the equation when a = -3. This implies that there is no solution for the given equation under the condition a = -3.
