how do I solve?
4X -4 = 24
4x - 4 = 24
+4 +4
4x = 28
4x/4 = 28/4
x = 7
to check:
4(7)-4 = 24
28- 4 = 24
To solve the equation 4x - 4 = 24, follow these steps:
1. Start with the equation: 4x - 4 = 24.
2. Add 4 to both sides of the equation to isolate the term with x. This will cancel out the -4 on the left side: 4x - 4 + 4 = 24 + 4.
3. Simplify: 4x = 28.
4. Divide both sides of the equation by 4 to solve for x. This will cancel out the 4 on the left side: (4x)/4 = 28/4.
5. Simplify: x = 7.
To check if your solution is correct, substitute x = 7 back into the original equation and see if both sides are equal:
4(7) - 4 = 28 - 4,
28 - 4 = 24.
As both sides of the equation are equal, the solution x = 7 is correct.
