2x+1=13 x=6 so an ok answer would be: 2x+10=40 x=15
Hmm, this answer is mathematically incorrect. If the question has no errors, 38 can go into 7 0 times, it can't because its bigger than 7.
However, if it were meant to be the other way round, how many times does 7 go into 38, the answer would be 5.
X=(b/2m)*y-e is the answer I believe.
