Question

3x-4(8+2)-7+10x=2x+3(6x+7)

Answer 1

Пошаговое объяснение:

3х-32-8-7+10х=2х+18х+21;

13х-20х=21+40+7

-7х=68

-х=68/7

$x = - 9 \frac{5}{7}$

Answer 2

Let's solve the equation step by step:

3x - 4(8 + 2) - 7 + 10x = 2x + 3(6x + 7)

First, simplify both sides of the equation:

3x - 4(10) - 7 + 10x = 2x + 3(6x + 7) 3x - 40 - 7 + 10x = 2x + 18x + 21

Next, simplify the expressions inside parentheses:

3x - 40 - 7 + 10x = 2x + 18x + 21 3x - 40 - 7 + 10x = 2x + 18x + 21 3x - 47 + 10x = 20x + 21

Combine like terms on both sides of the equation:

3x + 10x - 47 = 20x + 21 13x - 47 = 20x + 21

Next, move the variables to one side and the constants to the other side:

13x - 20x = 21 + 47 -7x = 68

Divide both sides of the equation by -7 to solve for x:

x = 68 / -7 x = -9.714

So the solution to the equation is x = -9.714.
