3\left(2x+4\right)-\left(7x-6\right)=30
Multiply both sides of the equation by 15, the least common multiple of 5,15.
6x+12-\left(7x-6\right)=30
Use the distributive property to multiply 3 by 2x+4.
6x+12-7x-\left(-6\right)=30
To find the opposite of 7x-6, find the opposite of each term.
6x+12-7x+6=30
The opposite of -6 is 6.
-x+12+6=30
Combine 6x and -7x to get -x.
-x+18=30
Add 12 and 6 to get 18.
-x=30-18
Subtract 18 from both sides.
-x=12
Subtract 18 from 30 to get 12.
x=-12
Multiply both sides by -1.
