To solve the equation 7x  (2x  4) = 39, first distribute the negative sign inside the parentheses: 7x  2x + 4 = 39. Combine like terms: 5x + 4 = 39. Subtract 4 from both sides: 5x = 35. Divide both sides by 5: x = 7. So, the solution to the equation is x = 7.

To solve the equation 7x  (2x  4) = 39:

Start by distributing the negative sign inside the parentheses: 7x  2x + 4 = 39

Combine like terms: 5x + 4 = 39

Subtract 4 from both sides to isolate the variable term: 5x = 35

Divide both sides by 5 to solve for x: x = 7
