To simplify the equation combine the like terms:

-2x^2 - 10x^2 = -12x^2

3-10 = -7

The simplified expression is -12x^2 + 5x - 7

-2x² + 3 + 5x - 10 - 10x²

Collect the like terms

-12x² + 3 + 5x - 10

Calculate the difference

-12x² - 7 + 5x

Use the commutative property to reorder the terms

-12 + 5x -7

$\huge\text{Hey there!}$

$\huge\textbf{Equation \#1.}$

$\mathsf{|-8| + 9 = }$

$\huge\textbf{Random note:}$

$\textsf{The additive inverse of }\mathsf{|-8|}\textsf{ is positive 8.}$

$\huge\textbf{Solving for the equation:}$

$\mathsf{|-8| + 9}$

$\mathsf{= \bold 8 + 9}$

$\mathsf{= 17}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\frak{17}}\huge\checkmark$

$\huge\textbf{Equation \#2.}$

$\mathsf{|-8 + 9| =}$

$\huge\textbf{Random note:}$

$\textsf{We will convert your equation to }\mathsf{-8 + 9}\textsf{ because it can make the equation}\\\textsf{a lot easier to solve.}$

$\huge\textbf{Solving for the equation:}$

$\mathsf{|-8 + 9|}$

$\mathsf{= -8 + 9}$

$\text{Start at }\rm{-8}\text{ and go \boxed{up} 9 spaces to the right and you have your answer.}$

$\mathsf{= 1}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\frak{1}}\huge\checkmark$

Mac's age is 3 years less than twice Joe's age. The sum of their ages is 30. Find their ages.

k0ka [10]

Answer:

Mac is 19 years old, Joe is 11 years old

Step-by-step explanation:

2J - 3 = M

J + M = 30

M = 30 - J

2J - 3 = 30 - J

3J = 33

J = 11

M = 30 - 11

M = 19
