Step-by-step explanation:
Answer:
<h2>22</h2>
Step-by-step explanation:
<h3>Given, y = 3 </h3>
substitute this value in given expression
<em>=> 10y - 8</em>
<em>=</em><em>></em><em> </em><em>1</em><em>0</em><em>(</em><em>3</em><em>)</em><em> </em><em>-</em><em> </em><em>8</em><em> </em>
<em>=</em><em>></em><em> </em><em>3</em><em>0</em><em> </em><em>-</em><em> </em><em>8</em><em> </em>
<em>=</em><em>></em><em> </em><em>2</em><em>2</em><em>.</em><em>.</em><em>.</em><em>ans</em>
<h2>HOPE IT HELPS U!!!!</h2>
So we have the system of equations:

equation (1)

equation (2)
To use substitution, we are going to solve for one variable in one of our equations, and then we are going to replace that value in the other equation:
Solving for

in equation (2):



equation (3)
Replacing equation (3) in equation (1):






equation (4)
Replacing equation (4) in equation (3):



We can conclude that the solution of our system of equations is <span>

Hello there!
Start by asking yourself:"How to find the percentage of a number?"
We need to use the equation y = P% * x
In this case, the y is 20%
Y = P% * X
Y = 20% * X
Now we need to convert the percentage to decimal
P = 20%/100
P = 0.2
Then go back to the equation
Y= 0.2 * 5
Y = 1
The answer is 1
I hope the steps are easy to understand and hopefully the answer helps!
