Question

solve the equation and check the solution

-4(T-6)-(T+7)=7

This is how I worked it out:

-4(T-6)-(T+7)=7
-4T-24-T+7=7
-11T+17=7

I think I should have -7 from each side, but not sure how.

Answer 1

here ill show you get ride of all that

Answer 2

ok

Answer 3

-4(T-6)-(T+7)=7

ok,
distribute --> -4T + 24 - T - 7 = 7
combine like terms --> -5T + 17 = 7
subtract 17 over
-5T = 10
divide by -5 and what do you get?

Answer 4

what is 10 / -5

Answer 5

-2

Answer 6

There is your answer

Answer 7

Do you understand?

Answer 8

yes, just all the negative and positive signs get me all confused,lol

Answer 9

thank you

Answer 10

negative * negative = positive
Negative * Positive = Negative

Answer 11

does it matter how large the number to determine the sign. For example: -17 + 5. because 17 is a larger number would that make it negative?

Answer 12

what do you think -17 + 5 is

Answer 13

I think it would be -12

Answer 14

yes

Answer 15

so would -17 - 5 = 22

Answer 16

no -17 - 5 is -22

Answer 17

you are ubtracting a positive number, to a negative so it becomes bigger on the negative side

Answer 18

-17-(-5) would be what?

Answer 19

-85

Answer 20

no -12

Answer 21

so basically I should use the sign of the larger number correct?
