Answer:
The answer is (4,4)
Step-by-step explanation:
I had this same problem and got it right so can you give me 5 stars:)
The solution of the system of equations –3x + y = –8 and x + 2y = 12 will be (4,4).
What is the equation?
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
Given,
–3x + y = –8 and x + 2y = 12
Multiplying by 2 to equation first
-6x + 2y = -16 and x + 2y = 12
Substracted equation second to first
7x = 28
x = 4
By substituting
y = 4
Hence "The solution of the system of equations –3x + y = –8 and x + 2y = 12 will be (4,4)".
