a. 6x+8 = 6(x+2)
6x+8 = 6x+12
8 = 12
There is no value of x which will make that true. So, no solution.
Now try the others. See whether there is a solution (solve normally), or whether the final sentence is true regardless of the value of x.
Tell whether each equation has one solution, infinitely many solutions, or no solution.
a. 6x + 8 = 6(x + 2)
b. 10x = 15 + 5x
c. x + 11 = 8x + 11 - 7x
