tìm số nguyên x : 17x-(-16x-37)=2x+43
\(17x-\left(-16x-37\right)=2x+43\)
\(17x+16x+37=2x+43\)
\(33x+37=2x+43\)
\(33x-2x=43-37\)
\(31x=6\)
\(x=\frac{31}{6}\notin Z\)
\(\Rightarrow x\in\varnothing\)
\(17x-(-16x-37)=2x+43\)
\(\Rightarrow17x+16x+37=2x+43\)
\(\Rightarrow33x+37=2x+43\)
\(\Rightarrow31x=43-37\)
\(\Rightarrow31x=6\Rightarrow x=\frac{6}{31}\)
P/S : Hoq chắc :>
Mà x\(\in Z\)nên \(\frac{6}{31}\notin Z\)
Vậy không có số nguyên x thỏa mãn

Tìm số nguyên x, biết : 17x-(-16x-37)=2x+43
\(17x-\left(-16x-37\right)=2x+43\)
\(=>17x+16x+37=2x+4\)
\(=>17x+16x+37-2x-4=0\)
\(=>31x+33=0\)
\(=>31x=-33\)
=> x=-33/31
17x-(-16x-37)=2x+43
=> 17x + 16x + 37 = 2x + 43
=> 17x + 16x - 2x = 43 - 37
=> 31x = 6
\(\Rightarrow x=\frac{6}{31}\)
Vậy \(x=\frac{6}{31}\)
\(17x-\left(-16x-37\right)=2x+43\)
\(17x+16x-37=2x+43\)
\(17x+16x-37-2x=43\)
\(x.\left(17+16-37-2\right)=43\)
\(x.\left(-6\right)=43\)
\(x=-\frac{43}{6}\)
