The answer is A.
A negative x a negative equals a positive so the square root of a negative value cannot be a negative value.
Answer:
x= -2
Step-by-step explanation:
suppose,
the number is x
so,
Four more than 6 times a number = 6.x+4=6x+4
9 times the number increased by 10 =9x+10
Now,
6x+4 = 9x+10
⇒9x-6x=4-10
⇒3x=-6
⇒x=- 6/3 [divide both sides by 3 ]
⇒x= -2
