Answer: -1 and 2

Step-by-step explanation:

a = 1st number

b = 2nd number

a + b = 1

a - b = -3

Use the elimination method. You will get

2a = 1 + -3 = -2

a = -2/2

a = -1

a + b = 1

Substitute a for -1

-1 + b = 1

Add 1 to both sides

b = 2

The two numbers are -1 and 2

Hope that helped!

Simplify – 2(7x – 3)

ANTONII [103]

All you need to do here is multiply the outside number by both 7x and -3.

When done correctly it should look like this:

-14x+6

Thats the answer.

7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.

negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive
