You can't solvd monomials because they are just 1 term multiplication :
example: 2a , or 14
For this case, the first thing we must do is define variables:
x: unknown number (1)
y: unknown number (2)
We now write the equations that model the problem:
their sum is 6.1:

their difference is 1.6:

Solving the system we have:
We add both equations:

Then, we look for the value of y using any of the equations:
Answer:
The numbers are:
Answer:
a = 1, b = 3.
Step-by-step explanation:
a + b = 4
a - b = -2 Adding to eliminate b:
2a = 2
a = 1
So 1 + b = 4
giving b = 3.
Answer:
3/5
Step-by-step explanation:
you need to subtract the two fractions then you can divide them by 2 to make them in their simplest form!
