Ignore the factor 7.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve :

Simplifying

x = 0

Solving

x = 0

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

Simplifying

x = 0

Subproblem 2

Set the factor '( - 2 + x)' equal to zero and attempt to solve :

Simplifying - 2 + x = 0

Solving - 2 + x = 0

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

Add '2' to each side of the equation.

- 2 + 2 + x = 0 + 2

Combine like terms : - 2 + 2 = 0

0 + x = 0 + 2

x = 0 + 2
