Find the value of x in the equation
-35 - (15x + 6) = 2 - 2(12x - 9)

Step 1

The given equation is -35 - (15x + 6) = 2 - 2(12x - 9)

Combine like terms on each side:
-35 - 15x -6 = 2 - 24x + 18.

Explanation:

Here we write the given equation and then combine like terms also.

Step 2

Move x terms to one side and move constant terms to another side
-15x + 24x = 20 + 41
9x = 61

Slove for x value \$x = (61)/9\$

So, the value of x is \$(61)/9\$.

Explanation:

Here first move x terms to one side and constant terms to another side then we solve for x value. Therefore, the solution to the equation is \$(61)/9\$.
