value of w-1 ⇒ 1-1 = 0 .

<u>Step-by-step explanation:</u>

We have , 16-7w=w+14-6 . We need to find value of w-1 . Let's find out:

⇒ $16-7w=w+14-6$

⇒ $(16-7w)-16=(w+14-6)-16$

⇒ $-7w=w-8$

⇒ $(-7w)+8=(w-8)+8$

⇒ $(-7w)+8=w$

⇒ $(-7w+8)+7w=w+7w$

⇒ $8=8w$

⇒ $\frac{8}{8}=\frac{8w}{8}$

⇒ $w=1$

So , value of w-1 ⇒ 1-1 = 0 .

The equation representing when the two planes would be at the same altitude is 9x=486

<h3>In terms of mathematics, what is an equation?</h3>

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

From (a) we get that: Altitude of Plane A = 990-18x

Altitude of Plane B = 1476-27x

make 890 - 18x = 1476-27x

-18x+27 x = 1476-890

9x=486

X= 54

so pass 54 seconds will the two plane at the same altitude.
