Answer:

16

Explanation:

3x - 4 =
(1)/(2)(10x - 72)

⇔ 6x - 8 = 10x - 72

⇔ 4x = 64

⇔ x = 16

The value of x that satisfies the equation is approximately 9.71.



To solve for x in the given equation:

10x - 72 = 3x - 4

We want to isolate x on one side of the equation. To do this, we can start by simplifying both sides of the equation.

On the left side, we can combine the terms with x by subtracting 3x from both sides:

10x - 3x - 72 = 3x - 3x - 4

Simplifying further, we have:

7x - 72 = -4

Next, we want to isolate the x term, so we can start by adding 72 to both sides of the equation:

7x - 72 + 72 = -4 + 72

Simplifying:

7x = 68

Finally, to solve for x, we divide both sides of the equation by 7:


(7x)/(7) =
(68)/(7)

This simplifies to:

x = 9.71 (rounded to two decimal places).
