Which equation can be rewritten as a linear equation after combining all like terms?

2x - 3 = 10x + 1 ... subtract 2x from both sides:

-3 = 8x + 1 ... subtract 1 from both sides:

-4 = 8x ... divide both sides by 8

-4/8 = x ... reduce the fraction

-1/2 = x

Or you could do:

2x - 3 = 10x + 1 ... subtract 10x from both sides:

-8x - 3 = 1 ... add 3 to both sides

-8x = 4 ... divide both sides by - 8

x = 4/-8 ... reduce the fraction

x = - 1/2
