Question

7 (6х-1)+3 (2х+1)-5 (12х-7)=23

Answer 1

7(6х-1)+3(2х+1)-5(12х-7)=23

42х-7+6х+3-60х+35=23

42х+6х-60х=23+7-3-35

-12х=-8

х=-8:(-12)

$x = \frac{2}{3}$

Ответ:

$x = \frac{2}{3}$

Answer 2

To solve the equation, let's simplify and solve for 'x':

7(6x - 1) + 3(2x + 1) - 5(12x - 7) = 23

Step 1: Distribute the terms inside the parentheses.

42x - 7 + 6x + 3 - 60x + 35 = 23

Step 2: Combine like terms.

(42x + 6x - 60x) + (-7 + 3 + 35) = 23

Step 3: Perform the operations inside the parentheses.

-12x + 31 = 23

Step 4: Isolate 'x' on one side of the equation.

Subtract 31 from both sides:

-12x = 23 - 31

-12x = -8

Step 5: Solve for 'x' by dividing both sides by -12.

x = (-8) / (-12)

x = 2/3

So, the solution to the equation is x = 2/3.
