=>3x+2x=12×(x-7)

=>5x=12x-84

=>5x-12x=-84

=>-7x= -84

=>x= -84/-7

=>x=12

Answer 2

Question :-

• Solve for x

$\frac{x}{4} + \frac{x}{6} = x - 6$

Solution :-

$\frac{x}{4} + \frac{x}{6} = x - 7$

Take lcm of 4 and 6= 12

Hence,

$\frac{3x + 2x}{12} = x - 7$

Now do cross Multiplication

$12x - 84 = 3x + 2x \\ \\ 12x - 84 = 5x \\ \\ 12x - 5x = 84 \\ \\ 7x = 84 \\ \\ x = \frac{84}{7} = 12 \: \: \: \: \: ans$
