8z + 3 - 2z < 51
6z + 3 < 51
6z < 48
z < 6 ☺
Yes, it is.
Technically there are no variables in this equation, as 47 minus 25 is equal to x (22)
The question doesn't describe any equation. An equation states that one number or expression is equal to another number or expression. The word 'equal' is nowhere to be found or implied in the question.
if the question u are asking is something like this 1/2 - ( - 1/2 ) then the answer is simple all you have to do is solve the equation like this 1/2 - ( - 1/2 ) = 1/2 + 1/2 = 2/2 = 1 its the - (-1/2) that is important remember the rule minus and minus equal plus plus and plus equal plus minus and plus equal minus remember and i hope it helps :)
When you are using non-standard definitions of "plus" and "minus", or of "equal".
It can't be solved because the discriminant of this quadratic equation is less than zero
a minus and a plus equal a minus number yeh dude
Yes, it is.
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus

Yes: the equation is tautological!
Yes that is correct
Yes it does. A minus is the opposite of something, so the minus of a minus is a plus.
It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
+ times a + = a plus- times a + = a minus- times a - = a plus+ times a - = a minus
