-3(x-5)+6(x+2)=9
7(x-9)-5(6-x)=-6+11x
10(x-7)-8(x+5)=6(-5)+24
Bài toán 3 : Tìm x, biết.
a. 2(x – 5) – 3(x + 7) = 14 b. 5(x – 6) – 2(x + 3) = 12
c. 3(x – 4) – (8 – x) = 12 d. -7(3x – 5) + 2(7x – 14) = 28
e. 5(3 – 2x) + 5(x – 4) = 6 – 4x f. -5(2 – x) + 4(x – 3) = 10x – 15
g. 2(4x – 8) – 7(3 + x) = |-4|(3 – 2) h. 8(x – |-7|) – 6(x – 2) = |-8|.6 – 50
k. -7(5 – x) – 2(x – 10) = 15 l. 4(x – 1) – 3(x – 2) = -|-5|
m. -4(x + 1) + 89x – 3) = 24 n. 5(x – 30 – 2(x + 6) = 9
o. -3(x – 5) + 6(x + 2) = 9 p. 7(x – 9) – 5(6 – x) = – 6 + 11x
q. 10(x – 7) – 8(x + 5) = 6.(-5) + 24
a.x/60=-3/4
b. 2/5=12/x
c. x-5/7 =6/21
dx+7/8 =63/24
e x/6=24/x
f .x+5= 4/x+5
g. x+12/x+8=4/3
h. x+9/x+7=9/8
7(x-9)-5(6-x)=-6+11x
10(x-7)-8(x+5)=6.(-5)+24
1:x là số nguyên
Tìm x biết:
a) 2(4x-8)-7(3+x)=|-4|.(3-2)
b) 8(x-|-7|)-6(x-2)=|-8|.6-50
c) -7(5-x)-2(x-10)=15
d) 4(x-1)-3(x-2)=-|-5|
e) -4(x+1)+(89x-3)=24
f) 5(x-30-2(x+6)=9
g) -3(x-5)+6(x+2)=9
h) 7(x-9)-5(6-x)=-6+11x
k) 10(x-7)-8(x+5)=6.(-5)+24
=> THANKS TRƯỚC !!!
a) -12+(x-9)<0 tìm x thuộc Z

mình cần rất gấp, giúp mình nha
1/ 10(X-7)-8(X+5)=6(-5)+24
2/ 8(X-|-7|)-6(X-2)=|-8|.6-50
3/ 2(4X-8)-7(3+X)=|-4|(3-2)
4/ 12(X-4)=6(x-2)-16(X+3)=7|-4|
5/ 4(X-5)-7(5-X)+10(5-X)=-3
bn nào giải giúp mik vs nha:)))
