Add 6.9 to both sides.
This is the new equation: 4.8y=10.08.
Next, divide both sides by 4.8.
new equation: y=2.1

Answer:

s = -24

Step-by-step explanation:

This is a 2-step linear equation, so can be solved the way all 2-step equations are solved.

<h3>Solution</h3>

Identify the constant term on the side of the equation with the variable term, and add its opposite to both sides.

$7 = \dfrac{1}{6}s+11\qquad\text{given}\\\\7-11=\dfrac{1}{6}s+11-11\qquad\text{add $-11$ to both sides}\\\\-4=\dfrac{1}{6}s\qquad\text{simplify}$

Multiply both sides by the inverse of the coefficient of the variable.

$(6)(-4)=(6)\left(\dfrac{1}{6}s\right)\qquad\text{multiply both sides by 6}\\\\\boxed{-24=s}\qquad\text{simplify}$

<h3>Alternate solution</h3>

Often, when equations contain fractions, you are advised to "eliminate fractions" as a first step. That generally means you multiply both sides of the equation by a suitable common denominator.

Here, the only denominator is 6, so the fraction can be eliminated by multiplying both sides of the equation by 6.

$7=\dfrac{1}{6}s+11\qquad\text{given}\\\\6(7)=6\left(\dfrac{1}{6}s+11\right)\qquad\text{multiply both sides by 6}\\\\42=s+66\qquad\text{simplify}\\\\42-66=s+66-66\qquad\text{add the opposite of 66 to both sides}\\\\\boxed{-24=s}\qquad\text{simplify}$

You will note this requires the same number of steps, but you don't have to mess with fractions after the first step.

<h3>Check</h3>

The value we found for the variable can be checked in the original equation.

$7=\dfrac{1}{6}(-24)+11\\\\7=-4+11\qquad\text{true}$
