Question

Wyznacz a.
A) aX -Y=Z
B) Ba-C=D
C)mn-6a=b
D)5a+M=N| -M
E) U+4a=W
F)5p+ar=3
G)-3r+2a=1

Answer 1

A)
aX-Y=Z /+Y
aX=Z+Y /:X
a= Z+Y / x

B)
Ba-C=D /+C
Ba=D+C /:B
a= D+c / B

C)
mn-6a=b /-mn
-6a= b-mn
-a= b-mn / 6
a = -b+mn/6

D)5a+M=N /-M
5a= N-2M /:5
a = N-2M /5

E) U+4a= W /-U
4a= w-U /:4
a= W-U / 4

F) 5p+ar=3 /-5p
ar=3-5p /:r
a= 3-5p / r

G)
-3r+2a=1 /+3r
2a = 1+ 3r /:2
a= 1+3r / 2
