x+43=2\left(x+15\right)
Add 28 and 15 to get 43.
x+43=2x+30
Use the distributive property to multiply 2 by x+15.
x+43-2x=30
Subtract 2x from both sides.
-x+43=30
Combine x and -2x to get -x.
-x=30-43
Subtract 43 from both sides.
-x=-13
Subtract 43 from 30 to get -13.
x=13
Multiply both sides by -1.
