Here is my solution for your given problem The given equation is 2y-[7-(5y-4)]=6 So you have to multiply the negative sign to the numbers within the close parenthesis 2y-[7-5y+4]=6 Then,add the like terms 2y-[-5y+11]=6 Multiply the negative sign to the enclosed numbers 2y+5y-11=6 Then,add the like terms and combine like terms 7y=6+11 Add the like terms 7y=17 Divide the following numbers to 7 to get the value of Y 7y/7=17/7 So the final answer is y=2.43
