2,5(0,6х-1,4)=-3,8(1,5х-0,8)+7,86Бырей плизз​

Answer 1

Ответ:

$2,5(0,6x-1,4)=-3,8(1,5x-0,8)+7,86\\1.5x-3.5=-5.7x+3.04+7.86\\1.5x-3.5+5.7x-3.04-7.86=0\\\\\\7.2x-14.4=0\\7.2x=14.4\\x=2$

x=2

Answer 2

2,5( 0,6х - 1,4) = -3,8(1,5х - 0,8) + 7,86
1,5х - 3,5 = - 5,7х + 3,04 + 7,86
1,5х + 5,7х = 10,9 + 3,5
7,2х = 14,4
х = 14,4/7,2
х = 2

Answer 3

To solve the equation 2,5(0,6x-1,4) = -3,8(1,5x-0,8) + 7,86, we can follow these steps:

Step 1: Distribute the coefficients through the parentheses on both sides of the equation.

2,5 * 0,6x - 2,5 * 1,4 = -3,8 * 1,5x + 3,04 + 7,86

1,5x - 3,5 = -5,7x + 10,9

Step 2: Collect like terms.

1,5x + 5,7x = 10,9 + 3,5

7,2x = 14,4

Step 3: Solve for x.

x = 14,4 / 7,2

x = 2

Therefore, the solution to the equation is x = 2.
