Question

slove for x: 2x+4/3x+6=4

Answer 1

Answer:

∴ x = -2

Step-by-step explanation:

2x+4/3x+6 = 4

or, 2x + 4 = 4 (3x+6)

or, 2x+4 = 12x + 24

or, 2x - 12x = 24 - 4

or, -10x = 20

or, x = 20/(-10)

∴ x = -2

Answer 2

Hope this helps you ;)

$\frac{2x + 4}{3x + 6} = 4$

$on \: cross \: multiplying$

$4(3x + 6) = 2x + 4$

$12x + 24 = 2x + 4$

$12x - 2x = 4 - 24$

$10x = - 20$

$x = \frac{ - 20}{10}$

$x = - 2$

BUT,

If u solve this by mathematical method then the ans will come out x= -2. But it is not a correct answer because on x= -2 , the LHS of the given euation is having form of (0/0) which is indeterminate form. Hence No Solution exist for this equation.
