We got the value of
by solving the given equations
and
by reduction method.
<h2>
What is reduction method?</h2>
The reduction or elimination approach includes using arithmetic operations between equations to produce equivalent equations with fewer unknowns that are simpler to analyze and evaluate.
Given equations are
.........(1)
...........(2)
We need to find the value of 
Simplifying the given equation (2) and we get
................(3)
Now, substitute the equation (3) in equation (1) and we get

Substitute the value of x in equation (3), we get

Now adding the values of x and y, we get
![\therefore e=\frac{26}{7}+\frac{52}{7}\\\Rightarrow e=-{[\frac{26+52}{7}]\\\Rightarrow e={[\frac{78}{7}]](https://tex.z-dn.net/?f=%5Ctherefore%20e%3D%5Cfrac%7B26%7D%7B7%7D%2B%5Cfrac%7B52%7D%7B7%7D%5C%5C%5CRightarrow%20e%3D-%7B%5B%5Cfrac%7B26%2B52%7D%7B7%7D%5D%5C%5C%5CRightarrow%20e%3D%7B%5B%5Cfrac%7B78%7D%7B7%7D%5D)
Therefore, the value of

1165 divided by 255 = 5.17 = 5 costumes
Answer:
To determine the number of shirts that Lisa can buy, knowing that each one is worth $ 14, that she can spend a maximum of $ 150 and that she will also buy a pair of jeans for $ 58 and a pair of shoes for $ 39, the following calculation must be performed:
(150 - 58 - 39) / 14 = X
53/14 = X
3.78 = X
53 - (14 x 3) = X
11 = X
Therefore, Lisa can buy 3 T-shirts, and she will have 11 dollars left over.

Answer:
15=a
Step-by-step explanation:
how I got this is because a triangle is equal to 180 so you have to add all of the things together then you get 12a=180 the reason why I got this is because if you add it so 6x+3a-1+3a+1 so you add common terms then you will equal to 12a then you divide it on both sides so then you equal to 15
