Tìm x
4x—15=50—(—25)—x
x(x+50=4x+5+x2
a.(x+50):4=32
b.(4x - 16) : 2 - 12 =4000
Tìm x
2x-50+3x-7=4x+120
Tìm x; y nguyên biết (4x-50).(y-6)=17
4x + 9 = - 26 - x
2x + 3x =75
- x - 2x = - 50 + 65
Tìm x
2x-50+3x-7=4x+120
a,5(3-2x)+5(x-4)=6-4x
b-5(2-x)+4(x-3)=10x-15
C,2(4x-8)-7(x-3)=|-4|(3-2)
d,8(x-|-7|)-6(x-2)=|-8|.6-50
Bài 1 : tính nhanh
a ) ( a - b ) - ( c - b ) -a
b ) - ( 300 - 400 ) + ( 300 - 400 ) + 100
bài 2 :tìm x biết
a ) 4x - 20 = 50 - ( 30 - 3x )
b ) 100 - ( - 5X ) = 40 - ( - 4x +10 )
c ) ( - 50 ) + ( - 7x ) = 100 - 8x
x+2x+3x+4x+10x+50=100
