Question

Solve the equation for b.
M = 4 b + 9 b x
Group of answer choices

b=M(4+9x)

b=4+9xM

b=4(M+9x)

Answer 1

Answer:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

b =  M /4  +  9 x

Answer 2

Answer:

b=M/(4+9x)

Step-by-step explanation:

In order to solve this you first have to factorize the b from the equation:

M = 4 b + 9 b x

M = B(4+ 9x)

As you can se ethe B is multiplying the factor (4+9x) so in order to clear B (4+9x) should go to the other side dividing M:

B=M/(4+9x)

And that would be the answer to solving the equation for B.
