The equations (5 - 3 = 2) and (5 + 3 - 3 = 5) are called identities because they hold true for all values of the variables involved. In these cases, they represent mathematical truths that are valid regardless of the context. An identity is a statement that is universally true and can be verified through algebraic manipulation, showing that both sides of the equation are equivalent for any input.
Equations that have letters are just called equations, but there are types 1, 2, 3, 4 and ratio type equations. Ratio type equations are the ones where it is a fraction on both sides of the equals sign. Equation (Type 2): x+1-5=12 Ratio Type Equation: 21/7=42-x/3
Yes, a fact family can have two equations, but typically it consists of four related equations that involve the same numbers. For example, with the numbers 2, 3, and 5, the fact family would include the equations 2 + 3 = 5 and 5 - 3 = 2, as well as 3 + 2 = 5 and 5 - 2 = 3. Each equation represents a different relationship among the same set of numbers.
A fact family consists of a set of related addition and subtraction or multiplication and division equations that use the same numbers. For the number 5, a simple fact family could involve the numbers 2, 3, and 5. The addition equations would be 2 + 3 = 5 and 3 + 2 = 5, while the corresponding subtraction equations would be 5 - 2 = 3 and 5 - 3 = 2.
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
Um there are an infinite number of equations but some simple ones are: X + 1 = 6 X + 2 = 7 123553X = 617765

If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
That depends. What are the equations?
6-3=3 and 5-2=3 and 4-1=3 and 3-0=3 and 2-(-1)=1

The answer will depend on statement 3 5 - whatever that may be!
It works out that the points of intersection between the equations of 2x+5 = 5 and x^2 -y^2 = 3 are at: (14/3, -13/3) and (2, 1)
equivalent equations
On a graph, parallel equations will run forever and never touch, whereas, perpendicular equations will make a right angle with each other.In an equation, parallel lines will have the same slope (the mx part of the equation).Ex:y = (1/3)x + 2y = (1/3)x + 4Perpendicular equations have negative reciprocal slopes of each other.Ex:y = (3/5)x + 6y = -(5/3)x + 4
No.
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
