You have to use the Periodic Table of elements.
P E M D A S
P - ( ) _Parenthesis
E - y2 _Exponents
M - X _Multiplication
D - / _Division
A - + _Addition
S - [-] _Subtraction
•6+2x4-2•
Multiplication comes fist so... 2 x 4 = 8
Addition comes next so... 6 + 8 = 14
Subtraction is last so... 14 - s = 12
x+x+2+x+4+x+6=42(x+x+x+x)+(2+4+6)=424x+12=424x=30x=15/2or 7 and 1/2
2/3 +x= 4/6 4/6+x=4/6 x=0
x=12 because 12 over 6 is 2,and 2 plus 4 is 6.
4x + 2 +2x - 6 = 0 6x -4 = 0 +4 +4 6x=4 x= 4/6 x=2/3
If: x+2 = y+6 Then: y = x-4
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
3x + 4 = x + 6 2x + 4 = 6 2x = 2 x = 1 Check it. 3 + 4 = 1 + 6 It checks.
3x = x + 4 x = 2 3x2=6 2+4=6
-2 cuz 6 + -2 = 4
-2
The answer to the equation 3 2x-4 plus 2 x plus 7 6 is 34x + 72.
6, 2
