7-2(x-4.5) = 6-4x

Simplify the left side of the equation by distributing the 2:
7 - 2x + 9 = 6 - 4x

Combine like terms on the left side:
16 - 2x = 6 - 4x

Add 2x to both sides of the equation:
16 = 6 + 2x - 4x

Simplify the right side:
16 = 6 - 2x

Subtract 6 from both sides:
10 = -2x

Divide by -2:
x = -5

Therefore, the solution to the equation is x = -5.
