2(x+4)=x+10

When solving equations like this, the most important thing to remember is that you must do the same thing to both sides. First multiply out the brackets, multiplying the x and the 4 by 2, giving 2x+8=x+10. We must then collect the x's on one side of the equals sign and the numbers on the other. To get rid of the x on the right hand side, minus x from both sides. This gives x+8=10. Then, to find the final solution we need to get rid of the 8, so it is subtracted from both sides: x+8-8=x and 10-8=2. Therefore, the answer is x=2.
