andrezito [222]

Answer:

The equation is 4x + 5 = 2x + 6

Step-by-step explanation:

The solution is $\frac{1}{2}$ means x = $\frac{1}{2}$

Let us put the coefficient of x in the left hand side = 4 and the coefficient of x in the right hand side = 2

∵ 4x - 2x = 2x

Now we need two numerical terms their difference is 1 like 5 and 6 or 6 and 7 or 7 and 8 or 8 and 9

Let us take 5 and 6

∵ 4x + 5 = 2x + 6

- Subtract 2x from both sides

∴ 2x + 5 = 6

- Subtract 5 from both sides

∴ 2x = 1

- Divide both sides by 2

∴ x = $\frac{1}{2}$

∴ The solution is $\frac{1}{2}$

The equation is 4x + 5 = 2x + 6

P(P|K) = 82.6%.

P(P|K) = P(K and P)/P(K) = 1.9%/2.3% = 0.019/0.023 = 0.8261 = 82.6%
