Answer:

<h3>x = 21/10y</h3>

Step-by-step explanation:

If the variables x and y vary inversely, this is expressed as;

x ∝ 1/y

x = k/y

k is the constant of proportionality

Given;

x = 7/2 and y = 3/5

Substitute;

7/2 =k/(3/5)

Cross multiply

k = 7/2 * 3/5

k = 21/10

Substitute the value of k into the formula;

x = k/y

x = (21/10)/y

x = 21/10 * 1/y

x = 21/10y

Hence the equation relating x and y is x = 21/10y

Let's solve your equation step-by-step.

6+2s−8s=18

Step 1: Simplify both sides of the equation.

6+2s−8s=18

6+2s+−8s=18

(2s+−8s)+(6)=18(Combine Like Terms)

−6s+6=18

−6s+6=18

Step 2: Subtract 6 from both sides.

−6s+6−6=18−6

−6s=12

Step 3: Divide both sides by -6.

−6s/−6

=12/−6

s=−2

Answer:

s=−2
