The equation is an identity.
Work Step by Step
Distribute through the parenthesis. $-0.6x+3+0.8x-4.8=0.2x-1.8$ Add/Subtract like terms. $0.2x-1.8=0.2x-1.8$ Subtract $0.2x$ and add $1.8$ to each side. Because you are left with the equal constants, any value of $x$ will satisfy the given conditions, therefore making the equation an identity. $0=0$
