–4b – 5 = 3b + 9 <br><br> I need help pls
Kitty [74]

The value of b in the equation is -2

<h3>What is an algebraic equation?</h3>

An algebraic equation is an expression that consists of numbers, variables with their arithmetic operations.

  • When solving this kind of algebraic equation, we move the like terms to a side and solve for the variable(unknown).

From the given algebraic equation:

-4b - 5 = 3b + 9

By collecting the like terms, we have:

-4b -3b = 5 + 9

-7b = 14

Divide both sides by (-7)

\mathbf{\dfrac{-7b}{-7} = \dfrac{14}{-7}}

x =  -2

goldenfox [79]

Answer:

The 96th term of the arithmetic sequence is -1234.

Step-by-step explanation:

first term (a)=1

second term (t2)=-12

common difference (d)= t2-a

d=-12-1

d=-13

96th term (t96)=?

We know that,

t96=a+(n-1)d

t96=1+(96-1)(-13)

t96=1+95(-13)

t96=1-1235

t96=-1234
