Online help with algebra homework problems 1:

Solving the given algebra sample equation and find out ‘a’ and ‘b’ value of theequation.

9a + 15b – 39 = 0

-9a + 20b – 31 = 0

Solution:

To find out the ‘a’ and ‘b’ the given algebra 1 value linear equation.

9a + 15b = 39

-9a + 20b = 31

Step 1: we are going to add equation (1) and (2). We get

9a + 15b = 39

-9a + 20b = 31

0a + 35b = 70

b = 2. This could also help us on factors of 36

Step 2: Now, we get the ‘b’ value as 2. In the equation (2) we substitute b = 2, we get

-9a + 20(2) = 31

-9a + 40 = 31

-9a = -9

a = 1

Now, we get the ‘a’ value as 1. So, the given system of linear equation values are a = 1, b = 2
