Question

4х-3(1+4х)=-5 И Помагите! :(

Answer 1

4х-3+12х= -5
4х+12х= -5+3
16х=-2
Х=16 : (-2)
Х=-8

Answer 2

Solving the Equation

To solve the equation 4x - 3(1 + 4x) = -5, we can follow these steps:

1. Distribute the -3 to the terms inside the parentheses: 4x - 3 - 12x = -5. 2. Combine like terms: -8x - 3 = -5. 3. Add 3 to both sides of the equation: -8x = -2. 4. Divide both sides of the equation by -8 to isolate x: x = -2/-8.

Therefore, the solution to the equation is x = 1/4 or 0.25.

Solution Verification

To verify the solution, we can substitute x = 1/4 into the original equation and check if both sides are equal:

4(1/4) - 3(1 + 4(1/4)) = -5 1 - 3(1 + 1) = -5 1 - 3(2) = -5 1 - 6 = -5 -5 = -5

Since both sides of the equation are equal, we can conclude that x = 1/4 is indeed the solution to the equation.

I hope this helps! Let me know if you have any further questions.
