Explanation

Answer

Problem

Solve the equation:
4(3b + 1) = 5b - 4

Step

After Multiplication

12 b + 4 = 5 b - 4

Formula:

Moving constant terms to right side and variable terms to left side we get

12 b - 5 b = -4 - 4

Step

Seperate variable

( 12 - 5 )b = -( 4 + 4 )

Step

After Simplification we get

7 b = -8

Step

Dividing 8 with the left 7

\$b= -8/7\$

Step

After Cancellation

\$b = -8/7 \$
