Question

(02.01) Solve for x: 2 over 5 (x − 4) = 2x.

Answer 1

Answer:

The equation having Single variable is:

   5 × (x -4)=2 x

Applying , Distributive property of multiplication with respect to Subtraction gives,

→5 x - 5×4=2 x

Subtracting , 2 x from both sides

→5 x -2 x -20= 2 x -2 x

→3 x-20=0

Adding 20, to both sides of the equation

→3 x-20+20=20

→3 x=20

$x=\frac{20}{3}$

Answer 2

2/5*(x-4)=2x

simplify 2/5*(x-4) to  2(x-4)/5=2x
multiply by 5             2(x-4)=10x
divide by 2                x-4=5x
subtract x                 -4=4x
divide by 4               -1=x
