If 5x + 5 (2 - x) + 10 = 4x - 6 then value of x is :
6.5
The question asks us to find the value of the variable x in the given linear equation:
$$5x + 5(2 - x) + 10 = 4x - 6$$
We need to simplify this equation step-by-step to isolate x.
First, let's distribute the 5 across the terms inside the parentheses on the left side of the equation:
$$5x + (5 \times 2) - (5 \times x) + 10 = 4x - 6$$
$$5x + 10 - 5x + 10 = 4x - 6$$
Now, combine the like terms on the left side. The terms involving x are 5x and -5x, and the constant terms are 10 and 10.
$$ (5x - 5x) + (10 + 10) = 4x - 6 $$
$$ 0x + 20 = 4x - 6 $$
$$ 20 = 4x - 6 $$
Next, we want to get all the terms involving x on one side and the constant terms on the other side. Let's add 6 to both sides of the equation:
$$ 20 + 6 = 4x - 6 + 6 $$
$$ 26 = 4x $$
Finally, to find the value of x, divide both sides by 4:
$$ \frac{26}{4} = \frac{4x}{4} $$
$$ x = \frac{26}{4} $$
Performing the division:
$$ x = 6.5 $$
The calculated value of x is 6.5. This matches the third option provided.
