2x+2(3x-2)+4-2(3x+8)
According to PEMDAS Parentheses Exponents Multiplication Division Addition Subtract, you must do the numbers in the parentheses.
2x+2(3x-2)+4-2(3x+8)
| |
2x+6-4+4-6x+16
Since there are no exponents, multiplication, and addition we do subtracting and adding. Which ever comes first in the equation.
2x+6-4+4-6x+16
Subtract the variables.
2x -6x = -4x
-4x+6-4+4+16
We cannot add variables and numbers together.
6-4=2
2+4=6
6+16=22
22 is a positive number so the answer is...
-4x+22
Hope it helps!
