Question

23+42:(8+3x) - 12=23​

Answer 1

Пошаговое объяснение:

X. = минус восемь третьих

Answer 2

Пошаговое объяснение:

42:(8+3х)-12=0

42/8+3х -12=0

42/8+3х=12

42=12•(8+3х)

42=96+36х

-36х+42=96

-36х=96-42

-36х=54

х= -3/2, хнедорівнює -8/3

х= -3/2

Відповідь: -3/2

Answer 3

To solve the equation for the variable "x," let's break down the steps:

Given equation: 23 + 42:(8 + 3x) - 12 = 23

1. Begin by performing operations inside the parentheses: 8 + 3x = 8 + 3x

2. Next, distribute the division operation (42) to both terms inside the parentheses: 23 + 42 / (8 + 3x) - 12 = 23

3. Subtract 23 from both sides of the equation to simplify: 42 / (8 + 3x) - 12 = 0

4. Add 12 to both sides of the equation: 42 / (8 + 3x) = 12

5. Now, isolate the fraction by multiplying both sides of the equation by (8 + 3x): 42 = 12 * (8 + 3x)

6. Distribute the multiplication on the right side: 42 = 96 + 36x

7. Subtract 96 from both sides of the equation: -54 = 36x

8. Finally, solve for x by dividing both sides by 36: x = -54 / 36 x = -3/2

So, the solution to the equation is: x = -3/2 or -1.5
