Assuming there are no parentheses:
2 times X - 1 + 4X - 6 + 2X =2X - 1 + 4X - 6 + 2X =
2X + 4X + 2X - 1 - 6 =8X - 1 - 6 =
8X - 7
It is 6X - 7.
Without an equality sign and not knowing the plus or minus values of some of the given terms the given expression can't be considered to be an equation.
-1?
44
Yes: the equation is tautological!
It is: x-1+4+7x-3 = 8x simplified
+ times a + = a plus- times a + = a minus- times a - = a plus+ times a - = a minus
7u.
It is: 10.2
negative b plus or minus the square root of b minus 4 times ac all over 2 a
x3-5x2+x is already simplified.
