Question

5(2х - 3) – 3(4х + 2) = 6(2х - 7)

Answer 1

Ответ:

10x-15-12x-6=12x-42

10x-12x-12x=-42+15+6

-14x=-21

x=21:14

x=1,5

Answer 2

To solve the equation, you'll need to simplify the expressions on both sides and isolate the variable $x$. Let's go step by step:

Given equation: $5(2x - 3) - 3(4x + 2) = 6(2x - 7)$

Step 1: Distribute the constants to the terms inside the parentheses: $10x - 15 - 12x - 6 = 12x - 42$

Step 2: Combine like terms on the left side of the equation: $-2x - 21 = 12x - 42$

Step 3: Move all terms involving $x$ to one side of the equation and the constants to the other side. To do this, you can add $2x$ to both sides and add 21 to both sides: $-2x - 12x = -42 + 21$

Simplifying the constants on the right side: $-14x = -21$

Step 4: Solve for $x$ by dividing both sides by -14: $x = \frac{-21}{-14}$ $x = \frac{3}{2}$

So, the solution to the equation is $x = \frac{3}{2}$, which is equivalent to $x = 1.5$.
