Work Step by Step

3(2-2x)=-6(x-1) To know if this equation is an identity, we have to solve it. 3(2-2x)=-6(x-1) Firstly, we have to multiply the number in front of the bracket with the numbers inside the bracket on both sides. 6-6x=-6x+6 Secondly, we have to collect like terms. 6-6=-6x+6x Now we subtract or add the numbers on both sides. 0=0x This equation is an identity because we got a 0 on both sides of the equation.
