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

<em>The two numbers are -1 and 2</em>

<em></em>

Hope that helped!

Find the sum<br>7/8+3/4 ​
ICE Princess25 [194]

Answer as an improper fraction =  13/8

This is equivalent to the mixed number   1 & 5/8

In decimal form, 13/8 = 1.625

=========================================

Work Shown:

3/4 = (3/4)*(2/2)

3/4 = (3*2)/(4*2)

3/4 = 6/8

----------

7/8 + 3/4

7/8 + 6/8

(7+6)/8

13/8

So 7/8 + 3/4 = 13/8
