Help with these 3 please

x=-12

Step-by-step explanation:

To remove the denominator we take LCD

LCD of 3  and 4  is 12

In the second step we multiply the whole equation by 12 not only the fractions

Now the denominator gets removed

1/3 * 12 = 4 , also 3/4 times 12 = 3*3 = 9

4x - 48 = 9x + 12

Subtract 9x on both sides

-5x - 48 = 12

Now add 48 on both sides

-5 x = 60

Divide both sides by -5

so x= -12

The value of x= -12
