Question

Solve this X/4+X/6=x-7

Answer 1

Step-by-step explanation:

$\\ \sf{:}\dashrightarrow \dfrac{x}{4}+\dfrac{x}{6}=x-7$

$\\ \sf{:}\dashrightarrow \dfrac{6x+4x}{24}=x-7$

$\\ \sf{:}\dashrightarrow \dfrac{10x}{24}=x-7$

$\\ \sf{:}\dashrightarrow 10x=24(7)$

$\\ \sf{:}\dashrightarrow 10x=168$

$\\ \sf{:}\dashrightarrow x=\dfrac{168}{10}$

$\\ \sf{:}\dashrightarrow x=16.8$

Answer 2

Answer:

1/12

Step-by-step explanation:

LCM of 4 and 6 is 12

x*3/4*3= 3x/12

x*2/6*2= 2x/12

3x + 2x /12 = x - 7

5x / 12 = x-7

5x = 12(x-7)

5x = 12x - 84

5x - 12x = -84

-7x = -84

x = -7/-84

x = 1/12
