Trả lời:
\(7\left(x-9\right)-5\left(6-x\right)=-6+11x\)
\(7x-63-30+5x=-6+11x\)
\(12x-93=-6+11x\)
\(12x-11x=-6+93\)
\(x=87\)
Vậy \(x=87\)

7.(x-9)-5(6-x)=-6+11x
<=>7x-63-30+5x=-6+11x
<=>12x-93=-6+11x
<=>12x-93+6-11x=0
<=>x-87=0
<=>x=87
Vậy x=87
7(x-3)-5(3-x)=11x-5
7(x-9)-5(6-x)=-6+11x
7(x-9)-5(6-x)=-6+11x
7(x-3)-5(3-x)=11x-5
-5(2-x)+4(x-3) =10x + 15 (tìm x)
7(x-9)-5(6-x)=-6+11x
xy+14+2y+7x=-10 (tìm xy)
a) -12+(x-9)<0 tìm x thuộc Z
b)x-(13-x)=-24+(-7+x)
c) (x - 7)+( 5-x)=12-(-8+x)
d)5(x-6)-2(x+3)=12
e)3(x-4)-(8-x)=12
f) 7(x-3)-5(3-x)=11x-5
g) 7(x-9)-5(6-x)=-6+11x
a) -12+(x-9)<0 tìm x thuộc Z
b)x-(13-x)=-24+(-7+x)
c) (x - 7)+( 5-x)=12-(-8+x)
d)5(x-6)-2(x+3)=12
e)3(x-4)-(8-x)=12
f) 7(x-3)-5(3-x)=11x-5
g) 7(x-9)-5(6-x)=-6+11x
-3(x-5)+6(x+2)=9
7(x-9)-5(6-x)=-6+11x
10(x-7)-8(x+5)=6(-5)+24
7 (x - 9) -5 (6 - x) = -6 + 11x
7(x-9)-5(6-x)=-6+11x
10(x-7)-8(x+5)=6(-5)+24
7 ( x – 9 ) – 5 ( 6 – x ) = -6 + 11x
