2\left(x+5\right)+4=x-2
Multiply both sides of the equation by 4, the least common multiple of 2,4.
2x+10+4=x-2
Use the distributive property to multiply 2 by x+5.
2x+14=x-2
Add 10 and 4 to get 14.
2x+14-x=-2
Subtract x from both sides.
x+14=-2
Combine 2x and -x to get x.
x=-2-14
Subtract 14 from both sides.
x=-16
Subtract 14 from -2 to get -16.
