To solve for b, we will substitute b = 10 back into the equation.

26 + 14(10) - 4(10) = 4
26 + 140 - 40 = 4
166 - 40 = 4
126 = 4

Therefore, the solution is incorrect. Let's recalculate.

We have:
26 + 14b - 4b = 4

Combine like terms:
26 + 10b = 4

Subtract 26 from both sides:
10b = -22

Divide both sides by 10:
b = -22/10
b = -2.2

Therefore, the correct solution is b = -2.2.
