Question

Solve the equation 2 over 5 (x - 2) = 4x for x.

Answer 1

\[{2 \over 5 } (x - 2) = 4x \]
multiply both sides of the equation by 5 ,
then divide both sides by 2

Answer 2

lastly add two to both side of the equation

Answer 3

Do I multiply everything by 5?

Answer 4

\[{2 \over 5 } (x - 2) = 4x\]
\[2+\frac12\left(5\times\left({2 \over 5 } (x - 2) \right)\right)=2+ \frac{5\times4x}2\]

Answer 5

yes

Answer 6

\[\frac{2}{5(x-2)}=4x\]\[{2 \over 5x-10}={4x}\]cross multiply\[2=4x(5x-10)\]\[2=20x^2-40x\]\[0=20x^2-40x-2\]now solve it using quadratic formula i.e;\[-b \pm \sqrt{b^2-4ac}\over2a\]

Answer 7
