This is not an equation (but an expression).  Without knowing the value of x, we cannot evaluate the expression.

Let me guess at what you're asking here:

"Find the value of x if (7x)(2x+27) = 0."

Then 14x^2 + 189x + 0 = 0   (this is a quadratic equation).

Then x(14x + 189) = 0, which leads to x=0 and x =-189/4.

I doubt that this is what you wanted.

Please ensure that you have copied down the entire original problem.

Solution for 7x=2x+27 equation:

Simplifying

7x = 2x + 27  

Reorder the terms:

7x = 27 + 2x

Solving

7x = 27 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

7x + -2x = 27 + 2x + -2x

Combine like terms: 7x + -2x = 5x

5x = 27 + 2x + -2x

Combine like terms: 2x + -2x = 0

5x = 27 + 0

5x = 27

Divide each side by '5'.

x = 5.4

Simplifying

x = 5.4
