Answer 2

because when you subtract a negative number with a positive number, you always use the sign of the bigger number

Answer 3

Addition of a negative is the same as subtracting positive numbers. Using this, figure out the values of each side, then find the correct statement.

Answer 4

OH okay thank you soo much!!

Answer 5

Remember what the last post said about adding negatives. Using that rule, find the value of the constant, then move it to the right side.

Answer 6

huh?

Answer 7

What would -6+-2 be?

Answer 8

b is a variable, but (-2) and 8 are constants. Since we're adding a negative, we have to subtract 2 from 8. 8 - 2 = 6. Move the six over to the right side of the original equation, then find the value of b
