Question

3x - 4(2.5) = 10

Explanation:

Step1: Simplify the left side

First, expand and combine like terms:
$3x - 4(2 - 2.5) = 3x - 4(-0.5)$
$3x - 4(-0.5) = 3x + 2$

Step2: Isolate the variable term

Subtract 2 from both sides:
$3x + 2 - 2 = 0 - 2$
$3x = -2$

Step3: Solve for x

Divide both sides by 3:
$x = \frac{-2}{3}$

Answer:

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