How can you check?
solve the equation ex: 2x + 17 = 9
2x = 9 -17
2x = -8
x = -8/2
x = -4 <-- this is the answer.
to check replace (substitute) this number into the original equation for x and simplify to see if bothe sides become the same number.
2x + 17 = 9
2(-4) + 17 = 9
-8 + 17 = 9
9 = 9 so the answer is correct. x = -4
