a) -12 . ( x - 5 ) + 7 .( -x + 3 ) = 5
b) 30 . (x + 2 )- 6 .( x - 5 ) - 24 .x = 100
ai nhanh nhat mk se k.lam on giup minh voi
\(a,-12.\left(x-5\right)+7.\left(-x+3\right)=5\)
\(-12x+60-7x+21=5\)
\(-19x+81=5\)
\(-19x=5-81\)
\(-19x=-76\)
\(x=4\)
\(b,30.\left(x+2\right)-6.\left(x-5\right)-24.x=100\)
\(30x+60-6x+30-24x=100\)
\(0x+90=100\)
\(0x=100-90\)
\(0x=10\)

tap hop cac so nguyen x: A=x-4/x-1 nguyen la {........}
GIUP MINH VOI
A=x-4/x-1 nguyên<=>x-4 chia hết cho x-1
<=>(x-1)-3 chia hết cho x-1
Mà x-1 chia hết cho x-1
=>-3 chia hết cho x-1
=>x-1 \(\in\) Ư(-3)={-3;-1;1;3}
=>x \(\in\) {-2;0;2;4}
