\(56-\frac{x}{34}=\frac{144}{96}\)

\(\Rightarrow\frac{x}{34}=56-\frac{144}{96}\)

\(\Rightarrow\frac{x}{34}=\frac{109}{2}\)

\(\Rightarrow2x=109\cdot34=3706\)

\(\Rightarrow x=3706\div2\)

\(\Rightarrow x=1853\)

Đơn giản biểu thức:

\(A=\left(a-b+c\right)-\left(b-c-d\right)+\left(c-d+a\right)\)

\(B=\left(a+b-c\right)+\left(b+c-a\right)-\left(a-c\right)\)

\(C=-\left(4a+5b-c\right)-\left(5b+3c\right)\)

\(D=\left(a-3b+c\right)-\left(2a-b+c\right)\)
