3\times 4+2\left(x+4\right)=30
Multiply both sides of the equation by 30, the least common multiple of 10,15.
12+2\left(x+4\right)=30
Multiply 3 and 4 to get 12.
12+2x+8=30
Use the distributive property to multiply 2 by x+4.
20+2x=30
Add 12 and 8 to get 20.
2x=30-20
Subtract 20 from both sides.
2x=10
Subtract 20 from 30 to get 10.
x=\frac{10}{2}
Divide both sides by 2.
x=5
Divide 10 by 2 to get 5.
