Answer 1

Hi Mikaela,

 

 

 

Solving equation (1) and (2) by adding them,

Substitute in equation (1),

The answer is 17 + 12=29

Answer 2

Hi Mikaela,

To solve this, we will need to set up a system of equations. Let's call one number a and the other b.

We know a + b = 29, and a - b = 5.

We can add the two equations together as such:

(a+b=29)

+(a-b=5)

2a=34

a = 17

Since a = 17, and we know a - b = 5, we can plug 17 in for a.

17 - b = 5

b = 17 - 5

b = 12

The answer is 17 + 12 = 29, and 17 - 12 = 5.
