Question

a / 6+2x=8-20

b/ x phần 8  = 3 phần -4

 

Answer 1

\(a,6+2x=-12\\ 2x=-12-6\\ 2x=-18\\ x=-18:2\\ x=-9\\ b,\dfrac{x}{8}=\dfrac{3}{-4}\\ x\cdot\left(-4\right)=8\cdot3=24\\ x=24:\left(-4\right)\\ x=-6\)

Answer 2

a: =>2x+6=-12

=>2x=-18

hay x=-9

b: =>x/8=-3/4

hay x=-6

Answer 3

a / 6+2x=8-20

=> 6+2x=-12

=>2x=-18

=> x=-9

KL

b/ x phần 8  = 3 phần -4

=> x/8=3/-4 => x/8= -6/8 => x= -6

Answer 4

\(a,6+2x=8-20\\ \Rightarrow6+2x=-12\\ \Rightarrow2x=-12-6\\ \Rightarrow2x=-18\\ \Rightarrow x=-9\\ b,\dfrac{x}{8}=\dfrac{3}{-4}\\ \Rightarrow\dfrac{x}{8}=\dfrac{-6}{8}\\ \Rightarrow x=-6\)

Answer 5

a: =>2x+6=-12

=>2x=-18

hay x=-9

b: =>x/8=-3/4

hay x=-6
