Im not sure if i did this correct, If it is algebra or Geometry than yes i did do it Right.
You set the Equations Equal: x+8 = 2x-5
THan you subtract the Smaller x which makes the new equation: 8= X-5
Than you: take the -5 away from the side with the x and add it to the other side of the equal side, New equation is: 13=X
This is your final answer: X=13
