Answer:
x=-2
Step-by-step explanation:
1. Convert base
(1/64) to (4^-3)
2.Apply exponent rule
4^-3(2x+10)
3. 4x-10=-3(2x+10)
4.Expand
4x-10=-6x-30
4x-10+10=-6x-30+10 (add 10 to both sides)
4x=-6x-20 (simplify)
4x+6x=-6x-20+6x (add 6 to both sides)
5. 10x=-20 (divide both side by 10)
6. Then you get x= -2.
