Answer:
x = 13
Step-by-step explanation:
(x+3) /2 = √64
do squre root
(x+3) /2 = 8
make two fraction with x and 3
[tex]\frac{x}{2} +\frac{3}{2} =8[/tex]
subtract 3/2 both sides
x/2 = 13/2
multiply both side by two and answer is
x = 13
[tex](x + 3) : 2 = \sqrt{64} \\ = > \frac{(x + 3)}{2} = 8 \\ = > (x + 3) = 8 \times 2 \\ = > (x + 3) = 16 \\ = > x = 16 - 3 = 13[/tex]
