7-4(3x-1)=5*(1-2x) ПОМОГИТЕ ПОЖАЛУЙСТА

Answer 1

7-12x+7=5-10x
12x-10x=7+7-5
2x=9
x=4.5

Answer 2

To solve the equation 7-4(3x-1)=5*(1-2x), we can follow the order of operations (PEMDAS/BODMAS) to simplify and isolate the variable x.

Step 1: Distribute the multiplication

We start by distributing the multiplication on both sides of the equation: 7 - 4(3x - 1) = 5(1 - 2x)

Simplifying the equation: 7 - 12x + 4 = 5 - 10x

Step 2: Combine like terms

Next, we combine like terms on both sides of the equation: 11 - 12x = 5 - 10x

Step 3: Isolate the variable

To isolate the variable x, we want to move all terms with x to one side of the equation and all constant terms to the other side. Let's move the terms with x to the left side and the constant terms to the right side: -12x + 10x = 5 - 11

Simplifying the equation further: -2x = -6

Step 4: Solve for x

To solve for x, we divide both sides of the equation by -2: x = -6 / -2

Simplifying the equation: x = 3

Therefore, the solution to the equation 7-4(3x-1)=5*(1-2x) is x = 3.
