9-4(2p-1)=41 — step-by-step solution

Let's solve in

ℝ

9 - 4 \cdot (2 p - 1) = 41

9 - (8 p - 4) = 41

9 - 8 p + 4 = 41

13 - 8 p = 41

- 8 p = 41 - 13

- 8 p = 28

p = \frac{28}{-8}

p = - \frac{28}{8}

▶Solution obtained:

p = - \frac{7}{2}

The numeric value of:

p = - \frac{7}{2}

equals:

▷

p = -3.5
