Odpowiedź:
a) X+ 3 K = L /-3K
X= L -3K
E+ X = 9F
X = 9F -E / -E
4G +X= H /-4G
X = H -4G
3P + X = 8R /-3P
X = 8P - 3P
b) X -7C= D /+7C
X= D + 7C
X -5M = N. / +5M
X= N + 5M
X - 3P= R /+3P
X = R + 3P
X -4A = 9B / +4A
X 9B + 4A
C)7MX=N /: 7M
X= N /7M
3PX = R / :3P
X = R/3P
PX= 2R / :P
X = 2R/P
3KX = 2L / :3K
X = 2L/3K
d) X/A = 1/2B /*A
X = 1/2BA
X/A =6B / *A
X = 6BA
X/5T = U /*5T
X = 5T * U
X/2M =5N /*2M
X = 5N *2M
