a + b = 42

b = 2a

a + 2a = 42

3a = 42

3a/3 = 42/3

a = 14

b = 2a

b= 2(14)

b = 28

hope this helps

So for this i would see what number i can multiply by to get 42.

Then i would see what number times = 42

7 x 6 = 42.

so then i would grab the 2 number and add
14 + 28 = 42.

Both of these number are in the 7 section. just find both numbers and add.
