\(2\cdot16>2x>4\)
\(\Leftrightarrow32>2x>4\)
\(\Leftrightarrow x\in\left\{3;4;...;15\right\}\)
\(2.16>2x>4\)
\(\Rightarrow2.16>2x>2.2\)
\(\Rightarrow16>x>2\)
\(\Rightarrow x\in\left\{15;14;13;12;...;5;4;3\right\}.\)
Vậy \(x\in\left\{15;14;13;12;...;5;4;3\right\}.\)
Chúc bạn học tốt!
Tìm x biết: 4/(x+2).(x+6) + 7/(x+6).(x+13) = 2x+1/(x+2).(x+16) - 3/(x+13).(x+16)

Các bạn làm được mình tick cho !
Tìm x biết: \(\frac{4}{\left(x+2\right).\left(x+6\right)}+\frac{7}{\left(x+6\right).\left(x+13\right)}=\frac{2x+1}{\left(x+2\right).\left(x+16\right)}-\frac{3}{\left(x+13\right).\left(x+16\right)}\)
Tìm x biết: \(\frac{4}{\left(x+2\right).\left(x+6\right)}+\frac{7}{\left(x+6\right).\left(x+13\right)}=\frac{2x+1}{\left(x+2\right).\left(x+16\right)}-\frac{3}{\left(x+13\right).\left(x+16\right)}\)
a, x/3=y/4=z/5 va x+y=16
b,x/4+y/3+z/5 va 2x+3y=-51
c,x/2=y/3=z/4 va x^2+y^2=52
d, x/3=y/4 va x^3 -y^3 =-37
Tìm x biết
|5(2x + 3)| + |2(2x + 3)| + |2x + 3| = 16
