Question

Wyznacz X :
Przykład: X-C=3D/+C
X=3D+C

B) X-7C=D

X-5M=N

X-3P=R

X-4A=9B

C)7MX=N

3PX=R


PX=2R

3KX=2L

D) X/A=1/2 B

X/A=6B

X/5T=U

X/2M=5N

DAJE NAJ!

Answer 1

X-7c=d|+7c
x=d+7c

x-5m=n|+5m
x=n+5m

x-3p=r|+3p
x=f+3p

x-4a=9b|+4a
x=9b+4a

7mx=n| :7m
x= n/7m

3px=r|:3p
x=r/3p

px=2r| :p
x= 2r/p

3kx=2l|:3k
x=2l/3k

x/a=1/2b|*a
x= 1/2ba

x/a=6b|*a
x=6ba

x/5t=u |*5t
x= 5tu

x/2m=5n|*2m
x= 10mn

licze na naj. :)
