Answer:
The solution to the system of equations is x=1/5 y= 0
Step-by-step explanation:
solving this system of equation using substitution method
5x-y=1 ….. equation (1)
-10x + 2y =-2 ….. equation (2)
Solving for value of x from equation 2
-10x =-2-2y
so x= -2-2y/-10 = - 2(1+y)/-10=
so x = 1+y/5......... equation 3
The second equation is solved for x, so we can substitute the expression 1+y/5 in for x in the first equation (1)
-10(1+y)/5+2y=-2
-2(1+y) + 2y = -2
-2-2y= -2
-2y= -2+2
y=0
Putting value of y in equation 3
x = 1+y/5.
x= 1+ 0/5 = 1/5
The solution to the system of equations is x=1/5 y= 0
We can check our work by plugging these numbers back into the original equations. Let's try 5x-y=1
5(1/5)-0=1
1 -0= 1
1=1
Yes, our solution checks out.
The solution of the word problem is a = 2
Word Problems are mathematical problems presented in complete languages, rather than in mathematical notations.
Example: Let a number is divided by half, the result is added to itself to give 6, what is the number?
Solution: Let the number be a
Now, dividing a by half, we get
a ÷ 
= 2a
Now, adding the result to the number itself, we will get 6 i.e.,
2a + a = 6
3a = 6
Dividing both the sides by 3, we get
a = 2
Therefore, the solution is a = 2
Complete question: Write your own word problem and share it with the group. Then translate your problem into its resulting math equation. What steps would you then follow to solve for the variable?

Try to visualize the situation; "A percent multiplied by $45 will be me $27"
$45(x/100)=$27
x/100=27/45
x/100=0.6
x=60%
Therefore, the discount was 60%
