Question

5×{10+3×[36:9+(16:a+2)-10]:6-8}:2=10

Answer 1

5x{10+3x[36:9+(16:a+2)-10]:6-8}:2=10
5x10+3x[4+(16:a+2)-10]:6-8=10x2
50+3x[4+(16:a+2)-10]:6-8=20
53x[4+(16:a+2)-10]:6=20+8
53x[4+(16:a+2)-10]:6=28
53x4+(16:a+2)-10=28x6
212+(16:a+2)-10=168
212+16:a+2=168+10
212+16:a+2=178
212+16:a=178-2
212+16:a=176
16:a=212-176
16:a=36
a=36x16
a=576

Answer 2

5×{10+3×[36÷9+(16÷a+2)-10]÷6-8}=10×2÷5=4
3×[36÷9+(16÷a+2)-10]÷6=4+10-10=4
36÷9+(16÷a+2)-10=4×6÷3=8
16÷a+2=8-4+10=14
a=14×16+2=224
