Twice a number decreased by 6 is equal to the sum of the nunber and 8

Answer 1

2x-6 = x + 8

x = 14

UNLESS, you meant twice (x-6) = x+8

then, 2(x-6) = x+8

2x-12 = x+8

x = 20

but PEMDAS, order of operations would require the 1st solution, x=14, as multiplication comes before subtraction. So, ignore x=20 unless the original problem had parentheses around (a number decreased by 6)
