2x – 4 = -4 (x – 5)
To solve the equation 2x – 4 = -4(x – 5), we will first distribute -4 to the terms inside the parentheses:
2x – 4 = -4x + 20
To solve the equation 2x – 4 = -4(x – 5), we will first distribute -4 to the terms inside the parentheses:
2x – 4 = -4x + 20.
Next, we will combine like terms by adding 4x to both sides:
2x + 4x – 4 = -4x + 4x + 20.
This simplifies to:
6x – 4 = 20.
To isolate the variable x, we will add 4 to both sides:
6x – 4 + 4 = 20 + 4.
This gives:
6x = 24.
Finally, to solve for x, we divide both sides by 6:
6x/6 = 24/6.
This simplifies to:
x = 4.
Therefore, the solution to the equation 2x – 4 = -4(x – 5) is x = 4.
