a/17.x+16.x+37-2.x=43
=>17.x+16.x-2.x=43-37=6
=>x.(17+16-2)=6
=>x.31=6
=>x=\(\frac{6}{31}\)
b và c tương tự

nho cho minh nha
Tìm số nguyên x:
a) -2x -(x-17)=34 -(-x+25)
b) 17x -(16x-37)=2x+43
c) -2x - 3.(x-17)=34-2(-x+25)
d) 17x + 3.(-16-37)=2x + 43 -4x
e) {-3x + 2.[45 - x - 3(3x + 7)-2x] + 4x}=55
