Question is: Andre solved an equation, but when he checked his answer he saw his solution was incorrect. He knows he made a mistake, but can’t find it. Where is andres mistake and what is the solution to the equation?
They messed up on step 4. instead of -2x it should be -10x. When they switched -6 over to the opposite side they forgot to use the opposite symbol. They did 6-4 instead of 4+6.
