Final Answer: $\boxed{3}$

Steps

Step 1 ：Distribute the -3 to both terms inside the parentheses: $-3(-5x+2) = 15x - 6$

Step 2 ：Combine like terms: $15x - 6 + x - 3 = 39$

Step 3 ：Simplify the equation: $16x - 9 = 39$

Step 4 ：Isolate the variable $x$: $16x = 39 + 9$

Step 5 ：Simplify further: $16x = 48$

Step 6 ：Divide both sides by 16 to solve for $x$: $x = \frac{48}{16}$

Step 7 ：Simplify the fraction: $x = 3$

Step 8 ：Final Answer: $\boxed{3}$
