3(x - 5) - 3(x + 6) = 10 + x
\(\Rightarrow\) 3x - 15 - (3x + 18) = 10 + x
\(\Rightarrow\) 3x - 15 - 3x - 18 = 10 + x
\(\Rightarrow\) -3 = 10 + x
\(\Rightarrow\) x = -13
2.(x-5)-3.(x+6)=10+x
tim x biet
cho x,y ti le thuan tim x biet x2=3,y1=-2,y2=\(\dfrac{3}{8}\) tim x2,y2biet y2-x2=-5,x1=-6,y1=4
tim x biet 2.(x+1)-3.(x+2)=10
Tim x,biet
a)(x-6)10=(x-6)8
tim x biet |x + 3| + 2|6 + 2x| + 2016 = 4016
tim x biet : /x+5/+/3-x/=8
tim x biet /x/+/x+2/=3
cho biet 2 dai luong x,y ti le nghich voi nhau va khi x=3 thi y=5
a,tim he so ti le b cua x doi voi y
b,hay bieu dien x theo y
c,tinh gia tri cua x khi y=-20;y=10
tim x,y biet
