3x - 2y = 5
-2x + 2y = -2
--------------------add
x = 3
3x - 2y = 5
3(3) - 2y = 5
9 - 2y = 5
-2y = 5 - 9
-2y = -4
y = -4/-2
y = 2
solution is (3,2)
ur system of equations is : 3x - 2y = 5 : -2x + 2y = -2
Answer:is -2 cause -2+-2.6=-4.6
Step-by-step explanation:
X=5
This is because you divide 20/4 since you divide 4 from each side.

Explanation:</h2>
We have the following System of Linear Equations in two variables:
So let's call this as SYSTEM A. Two systems of equations are said to be equivalen if and only if they have the same solution, so we can get an equivalent system, called SYSTEM B, by multiplying an equation by some constant value. Let's say we multiply equation (1) by 2, then:
In conclusion:
SYSTEM A:
SYSTEM B:
SYSTEM A and SYSTEM B are equivalent

Step-by-step explanation:
In order to solve this problem, we must follow bedmas rules. This acronym can be written in multiple ways such as pedmas or bodmas. However, they all mean the same thing. They tell us the order we must follow in order to solve arithmetic equations. The B or P stands for brackets or parentheses, respectively. This means that we must solve the statement within the statement. E or O stands for exponents or order, respectively. This means that the next step will be to solve any powers within the statement. D and M mean division and multiplication, respectively. Notice how I grouped D and M together. This is because division and multiplication can be solved in the order they are given in (left to right). Lastly, we have A and S which mean addition and subtraction, respectively. Like division and multiplication, addition and subtraction are solved in the order they are given in.
Now that we know the rules, let's solve this problem.
We immediately see brackets in this expression so let's solve the statement within.
(16-15)^2 + 9
Notice how I did the multiplication first since DM comes before AS
(1)^2 + 9
1+9
