2k - 3(h - 5k) = 2k - 3h + 15k = 17k - 3h

-(3x-4) = -3x + 4
I advise that you ask us about each problem one at a time. Tell us the problem and we will see if we can simplify it for you.
It is: (3x+4)(2x-3) when factored
-x-6-(-11x) + (-1) Remove the brackets: -x-6+11x-1 Collect and simplify like terms: 10x-7 A - - is equal to a +
3
-(3x-4) = -3x + 4
It means a minus, in other words its a loss. It means a minus, in other words its a loss.
3(p+7) - (4p-1) = -5(2p-3) + 1 Multiplying out the brackets: 3p + 21 - 4p + 1 = -10p + 15 + 1 Simplifying: 22 - p = 16 - 10p 9p = -6 p = -2/3 To check, you could substitute p = -2/3 into the original equation and check that it holds.
he established the use of of plus,minus signs,brackets,and braces.
Yes, both brackets will contain a minus sign. (x -2)(x-6)

Generally it is additions and subtractions on a left to right basis. So if a minus comes before a plus, the minus is done first and the plus last. If a plus comes before a minus, then the plus is done first and then the minus. It can be more complex than that, when you bring other elements into calculations. Things inside brackets are all done before anything outside brackets. In that case, were there pluses and minuses inside brackets and only multiplications outside, then the pluses and minuses would be done before the multiplications. BOMDAS is a way of remembering the order to do things in: Brackets, power Of, Multiplication, Division, Addition, Subtraction. There are other variations of this: Parantheses, Exponentiation, Division, Multiplication, Addition, Subtraction.
The minus sign: - Negative values can also be indicated by showing them in red or having brackets around them.
In an algebraic expression, terms are the elements separated by the plus or minus signs. On simplifying further we get: 8 - 5x and it has two terms: 8 & -5x. But, without simplifying we have four terms which are 3x, 8, -2x & -6x.
If you mean (4+3)/12-(2+3)/4, the answer is -2/3.
one will contain a minus sign and the other will contain a plus sign
