To show the subtraction equation 15 - 7, you can represent it with the following two equations: 15 - 7 = 8 and 8 + 7 = 15. The first equation directly shows the subtraction, while the second equation demonstrates the relationship by adding the subtracted number back to the result.
What else can I help you with?
What property used to solve subtraction equations?
The property commonly used to solve subtraction equations is the "Subtraction Property of Equality." This property states that if you subtract the same number from both sides of an equation, the two sides remain equal. For example, if you have the equation (x - 5 = 10), you can add 5 to both sides to isolate (x), giving you (x = 15). This principle is essential for maintaining balance in equations while solving for unknowns.
What is a property of equality used to solve subtraction equations?
One key property of equality used to solve subtraction equations is the Subtraction Property of Equality. This property states that if you subtract the same number from both sides of an equation, the two sides remain equal. For example, if ( a = b ), then ( a - c = b - c ) for any number ( c ). This allows us to isolate variables and find their values effectively.
How could you show that two equations aren't equivalent?
One way would be to solve the two equations. If they have exactly the same solution set, they are equivalent. Otherwise they are not.
When solving two-step equations what must be undone first?
You have to follow the order of operations which goes as follows, parentheses, then exponents, then multiplication, then division, then addition, and finally subtraction
Algorithm for subtraction of two numbers?
read the value A,b store the result of subtraction of a,b in continer subtraction display subtraction
Is addition and subtraction examples of equations?
Addition and subtraction are mathematical processes. They can be used in equations, which are statements that the values of two mathematical expressions are equal, but they are not equations by themselves.

The two equations 74 plus 13 equals 87 and 87-13 equals 74 demonstrates what kind of operation?
The two equations 74 + 13 = 87 and 87 - 13 = 74 demonstrate the inverse relationship between addition and subtraction. In the first equation, adding 13 to 74 gives you 87, while in the second equation, subtracting 13 from 87 returns you to 74. This showcases how addition and subtraction are inverse operations, with subtraction "undoing" the action of addition.

What is two step equations is?
A two Step equation is simply an equation that requires two steps to solve it.Example3h + 4 = 16 *Get the Variable by itself- when doing that know thataddition and Subtraction always come before Multiplicationand subtraction. - 4 = - 43h = 123h / 3 = 12 / 3h = 12 / 3 => h = 4

What two numbers add up to 157?
149+8=157 or 139+18=157
What two numbers multiplied equal 157?
1 and 157.
What is the significance of the symbol "c" in mathematical equations?
The symbol "c" in mathematical equations represents "not equal to." It is used to show that two quantities are not the same or not equal to each other.
What are the factors of subtraction?
Finding the difference of two numbers is known as subtraction.
