Answer:
First number = 4
Second number = 9
Step-by-step explanation:
If the first number = x, the second number = x + 5.
The calculation can be expressed as follows:
x + 2(x + 5) = 22
First, expand the bracket 2(x + 5):
x + 2x + 10 = 22
Combine like terms:
3x + 10 = 22
Subtract 10 from both sides:
3x = 12
Divide both sides by 3:
x = 4
First number = 4
Second number = 4 + 5 = 9
Positive 28 because to negative will equal a positive number
The constant is 3 because it has no variable.
The coefficient is 7b because it has a variable.
First divide both sides by - 5,

Move the constant to the right side of the equation and change its sign (-4 => +4)

Add the numbers,
