5x 5 is the coefficient and x is the variable.
The last one is an example of like terms.
x = 1
5x - 3 + x - 9 = 5x Bring like terms together of the left side: 5x + x - 3 - 9 = 5x Combine like terms: 6x - 12 = 5x Add 12 to both sides: 6x = 5x + 12 Subtract 5x from both sides: x = 12
It is: 2x and 5x are like terms Addition: 2x+5x = 7x Multiplication: 2x*5x = 10x2
Since 5x is a factor of both terms, divide it. 5x3 + 5x = 5x(x2 + 1)
5x and 10x
5x + 9y-3 is a trinomial term true of false
5x 5 is the coefficient and x is the variable.
the coefficient
It is 1 term of an algebraic expression in the form of 5x
The last one is an example of like terms.
Oh, dude, it's like super simple. The terms of that expression are 5x, -3y, and 4. Each of those is a term because they're separated by those plus and minus signs. So, like, that's it.
x = 1
If it's inside the brackets it means that it belongs to that specific term, but if it was outside the brackets, it means that every term inside the brackets goes out with opossite sign. For example: [ -5x + 6y ] = -5x + 6y , the negative is only for 5x, but if you had - [ -5x + 6y] = 5x - 6y , every term inside the bracket goes out with opossite sign.
By comparing it to another term.
5x - 3 + x - 9 = 5x Bring like terms together of the left side: 5x + x - 3 - 9 = 5x Combine like terms: 6x - 12 = 5x Add 12 to both sides: 6x = 5x + 12 Subtract 5x from both sides: x = 12
