Wyznacz X
C=X+B X=?
X+B=C l -B
X=C – B

D=X – M X=?
X – M=D l +M
X= D+M

K=X*S X=?
X*S=K l :S
X= K:S
R= X: T X=?
X:T = R l *T
X= R*T
3C= X +2B X=?
X+2B=3C l-2B
X=3C – 2B

5D=X – 4M
X-4M=5D l +4M
X= 5D+4M

3K=X*5S
X*5S=3K l :5S
X= 3K : 5S
9R=X:3T
X:3T=9R l *3T
X=9R:3T

2X+ A= B l -A
2X=B – A l :2
X = (B – A):2
X=

3X – 2K= 5M l +2K
3X=5M+2K l :3
X=
4X*5K=3S
5X:2T=3R
4D+3X= K+M




2X-5P=A-2B
5X*2C=4M+3B plis na szybko
