Answer: y=20

Explanation:

To solve the equation, we first need to add 15 to 85.

15+85=100

Next, we divide 100 by 5 which gives us the answer 20.

y=20

Answer:

y = 20

Explanation:

Hi! Our task is to solve the equation
$\sf{85=5y-15}$ .

So, first, I'll subtract 85 from both sides:

$\rightarrow \sf{-5y=-15-85}$

$\rightarrow \sf{-5y=-100}$

Simplify:

$\rightarrow\sf{5y=100}$

Next, divide both sides by 5:

$\rightarrow \sf{y=20}$

Therefore, the value of y is
$\sf{20}$ .

We will now make sure that 20 is indeed the correct value of y.

The way we'll do that is we'll substitute 20 for y:

$\twoheadrightarrow\bf{85=5(20)-15}$

$\twoheadrightarrow\bf{85=100-15}$

$\twoheadrightarrow\bf{85=85}$

A true statement indicates that y = 20 is indeed the solution of this equation.
