Linear Equations. Solve the equation 5 = 3y +6 using inverse operations.

agasfer [191]

Answer:

The value of $y=\frac{-1}{3}$ .

Step-by-step explanation:

Considering the equation

$5 = 3y +6$

To solve the equation $5 = 3y +6$ using inverse operations,

Subtracting 6 on both sides of the equation,

$5-6 = 3y +6-6$

Simplifying,

$-1 = 3y$

Dividing both sides by 3

$\frac{-1}{3} =\frac{3y}{3}$

$\frac{-1}{3} =y$

Switching both sides

$y=\frac{-1}{3}$

Therefore, the value of $y=\frac{-1}{3}$ .
