D) 2

Step-by-step explanation:

$5x+7\leq8x-3+2x\qquad\text{combine like terms}\\\\5x+7\leq(8x+2x)-3\\\\5x+7\leq10x-3\qquad\text{subtract 7 from both sides}\\\\5x\leq10x-10\qquad\text{subtract}\ 10x\ \text{from both sides}\\\\-5x\leq-10\qquad\text{change the signs}\\\\5x\geq10\qquad\text{divide both sides by 5}\\\\x\geq2\\\\\ x=2,\ \text{because}\ 2\geq2,\ (\geq-\text{greater than or equal to}),\ \text{2 is equal to 2}.$

I’m going to assume you forgot the square in the transformation so i can answer this question :)
