Answers

Answer 1
Answer: Step 1: Simplify both sides of the equation.
2/5(x-2)4x

Simplify: (show steps)
2/5x+-4/5=4x

Step 2: Subtract 4x form both sides.
2/5x+-4/5-4x=4x-4x

Step 3: Add 4/5 to both sides.
-18/5x+-4/5+4/5=0+4/5

Step 4: Multiply both sides by 5/-(18).

(5/-18)*(-18/5)*=(5/-18)*(4/5)



Then your answer would be      -2
                                              x=  -----
                                                      9
Answer 2
Answer: (2/5)(x-2)=4x
multily both sides by 5/2 (2/5 times 5/2=10/10=1)
1(x-2)=20x/2
x-2=10x
minus x both sides
-2=9x
divide 9
-2/9=x
