DK. x≥1/2

=\(\sqrt{\left(2x-1\right)^2}-\sqrt{\left(2x+1\right)^2}=2x-1-2x-1\)

=-2

A= 1\(-\dfrac{1}{35}\)=\(\dfrac{34}{35}\)

B=\(\dfrac{17}{12}-\dfrac{7}{12}=\dfrac{10}{12}\)

.

A=d

B=2b-10c+17

C=-a-13b-2022

a)\(\text{5x-12=3x+26=>x=19}\)

b)\(\text{17-4x=3x-28}=>x=\dfrac{45}{7}\)

c)\(\text{4(x-2)-15=3(x+1)+9=>x=33}\)

d)\(\text{29-2(2x+3)=-14-3(3x-1)}=>x=\dfrac{34}{5}\)
