Answer:
m + n = 15
m - 3 = n
The numbers are 9 and 6
Step-by-step explanation:
From the question,
The sum of two numbers is fifteen; the first number is m and the second number is n. To translate to a system of equations, we can write that
m + n = 15 ..... (1)
Also, from the question,
One number is three less than the other,
Also, to translate to a system of equations, we can write that
m - 3 = n ...... (2)
If desired, we can determine m and n
From equation (1)
m + n = 15
Then,
m = 15 - n ...... (3)
Put the value of m in equation (3) into equation (2)
m - 3 = n
Then
15 - n - 3 = n
15 - 3 = n + n
12 = 2n
n = 12/2
∴ n = 6
For m, put the value of n into equation 3
m = 15 - n
m = 15 - 6
m = 9
∴ m = 9 and n = 6
Hence, the numbers are 9 and 6

Answer:
Step-by-step explanation:
So we have the equation:
And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.
On the left, the 2y cancel. Simplify the right:
And we're done!
Step-by-step explanation:
m = -91.3
Since you move from 91.3 to the other side of the equal sign, it becomes a negative number (-91.3)
Think of the equal sign as a seperator from the positive and negative side.
If you also get an equation like -x=91.3, just flip the -x, to x, and change the 91.3 to a negative 91.3!
Cheers!
