2a + 7b = -1

3a - 7b = -5

The system of equations can be solved by elimination:

2a + 3a = -6

5a = -6

a = -6/5

substitute the value of a in any of the two original equations to find the value of b:

2(-6/5) + 7b = -1

-12/5 + 1 = -7b

-7/5 = -7b

b= 1/5

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What can you do to make learning algebra easier?

Sometimes you can think of things instead of letters, for example...3a + 2a = ?If that was 3 apples plus 2 apples equals ... ? then you could do it, right?3 apples + 2 apples = 5 apples3a + 2a = 5aAnd the same with MINUS...10b - 7b = ?10 bananas - 7 bananas = 3 bananas10b - 7b = 3bOf course, you can't add bananas and apples, you have to count them separately, so...3a + 4b + 7a - 2b= 3 apples + 4 bananas + 7 apples - 2 banana= 10 apples + 2 bananas= 10a +2b(You can't add these two together)After that it gets more complicated...
