Add '-3b' to each side of the equation.
3 + 4b + -3b = -7 + 3b + -3b

Combine like terms: 4b + -3b = 1b
3 + 1b = -7 + 3b + -3b

Combine like terms: 3b + -3b = 0
3 + 1b = -7 + 0
3 + 1b = -7

Add '-3' to each side of the equation.
3 + -3 + 1b = -7 + -3

Combine like terms: 3 + -3 = 0
0 + 1b = -7 + -3
1b = -7 + -3

Combine like terms: -7 + -3 = -10
1b = -10

Divide each side by '1'.
b = -10

Simplifying
b = -10
