just work backwards from the answer, 133. first, divide by seven (as that is the opposite of multiplying) and you get 19. subtract 5 from that number (subtraction is the oppostie of adding) and you get 14, which should be your answer. To check it, use that answer to do the problem correctly. 14 plus five is 19, multiplied by 7 is 133. hope that makes sense! anyhow, original number is 14

you have to put it in the form first...
(x+5)7=133
then work it out....
divide (x+5) by 7 as you divide 133 by 7
itll read (x+5)=19
then subtract 5 from each side x=14

divide 133 by 7 to get the number

133 / 7 = 19

14 + 5 = 19

19 x 7 = 133

The original number is 14

all you have to do is divide by seven, and then subtract five

the answer is 14.

14 plus 5 equals 19. 19 times seven equals 133.

hope this helps!

# is x.... so plus 5 and times 7.... write the equation....
(x+5)7 = 133
divide by 7 in both sides to get rid of the 7 and maintain the equation balanced....
(x+5) = 19
subtract 5 in both sides so the left is x and the final value is 14!!

x = 14

First of all math is spelled M-A-T-H not M-A-T-G. You should also be figuring this out by yourself if this is homework, divide 133 by seven, then subtract five and you have your answer.

133 / 7 -5 =14
