Answer:
x= -1
Step-by-step explanation:
the equation would be written like this
2+16x= -7x-21
add -7x on both sides
2+23x= -21
subtract 2 from each side
23x= -23
divide by 23 on both sides
x= -1

Answer:
66%
Step-by-step explanation:
Let u represent the <em>number</em> from the USA. Then the number from Singapore is u-120. The given relationship is the fraction of participants from Singapore:
(u -120) = 0.26(u +(u -120) +24)
u -120 = 0.52u -24.96
0.48u = 95.04
u = 198 . . . . . . . . divide by the coefficient of u; participants from the USA
Then the <em>fraction</em> from the USA is ...
u/(2u-96) = 198/300 = 66% . . . percentage from the USA
