I'm confused, is it A or D?

Answer:
D. x>7
Step-by-step explanation:
Multiply - and -3
x+3>10
Subtract 3 on both sides
x>7
(Remember you can only switch the symbol if you divide or multiply by negative it does not apply on addition or subtraction)
Hope this helps!
Answer:
It is D.
Step-by-step explanation:
Remove parentheses: x + 3 > 10
Subtract 3 from both sides: x > 10 - 3
Simplify 10 - 3 to 7: x > 7
