1 + 1 2 ⋅ (4x − 6) = −2

Dmitry [639]

1.4375

<u>Step-by-step explanation:</u>

Step 1:

Let the given equation be $1+12(4X-6)=-2$

To find X simplification of terms using BODMAS ( Brackets Orders Division Multiplication Addition Subtraction) is done as follows.

Step 2:

Let us expand the equation as $1+ (12*4X)-(12*6)=-2$

Step 3:

Let us expand it further as $1+48X-72=-2$

Step 4:

To find X segregate X in one side and all other remaining terms in other side as follows

$48X=-2+72-1$

After the simplification the numerical value is

$48X=69$

Step 5:

Keep X along one side and bring 48 to the denominator of another side to find X as follows

$X=69/48$

And the value of X is 1.4375
