Answer:
v=1/100
u=1/80
Step-by-step explanation:
160u + 600v = 8
multiplying both sides by 3
480u + 1800v = 24.........(i)
240u + 520v = 41÷5
multiplying both sides by 2
480u + 1040v = 82÷5............(ii)
(i)-(ii)
+480u-480u +1800v-1040v = 24-82÷5
760v=(120-82)÷5
v=38÷(5×760)
=1/100
=0.01
160u=8-600×1/100
=8-6
u=2/160
=1/80

Answer:
Step-by-step explanation:
160u plus 600v = 8 eq1
240u plus 520v = 8.2 eq2
eq1[3] ,eq2[2]
480u plus 1800v = 24 eq3
480u plus 1040v = 16.4 eq4
eq
3-eq4
760v=78.6
v=1/2
substitute v as 1/2 in eq1
u= -73/40
u=
