43 never changes ... it's always 43 ... so 43 is a constant.
'x' is the variable.
x(x + 1)(x -1)
Not always. It could be a constant. For example x is one variable, and y = x-2 is another variable. Then x - y = x - (x-2) = 2.
8
Since the variable is the same, you can use the distributive property for this one. That is, subtract -8 minus 4, and attach the variable, "x", to the result.
It is "False" (which is a Boolean variable)
x(x + 1)(x -1)
Not always. It could be a constant. For example x is one variable, and y = x-2 is another variable. Then x - y = x - (x-2) = 2.
7 minus x cannot be solved with more information, because x is an unknown variable.
X is a variable. So you subtract 7 minus 2 to find the variable answer.So your answer is 5
8
Since the variable is the same, you can use the distributive property for this one. That is, subtract -8 minus 4, and attach the variable, "x", to the result.
x=28
It is "False" (which is a Boolean variable)
a variable minus a number and the same variable is b-6b= -5b
The only number in that whole string of words whose value you don't already know, and can change from one minute to the next, is 'x'.
"10x - x" is basically 10 x's minus one x. The answer is 10 minus 1, but in terms of x. Since 10 minus 1 is 9, the answer is 9x.
