Perform the addition.
You know that 6 cows plus one cow is 7 cows, 6 kittens plus 1 kitten is 7 kittens,
and 6 computers plus 1 computer is 7 computers.
It should not surprise you to discover that [ 6x + 1x ] = 7x .
-9
15xy-2xy-7x+x=13xy-6x
To simplify the expression (4x + 6x), you combine like terms by adding the coefficients of (x). This gives you (4 + 6 = 10), so the simplified expression is (10x).
6x-2y
Simple,its just like this: 6x+1+7-3 =6x+8-3 =6x+5
-9
15xy-2xy-7x+x=13xy-6x
6x + 9 + 2x = 8x + 9
To simplify the expression (4x + 6x), you combine like terms by adding the coefficients of (x). This gives you (4 + 6 = 10), so the simplified expression is (10x).
Well, honey, you just add those like terms together. 5x plus x is the same as 6x. It's as simple as that, darling.
7x + 7 + 6x - 9 = 13x - 2
x + 2x + 6x = 9x
6x-2y
x^2-4x/x^2-6x+8 = x(x-4)/(x-2)(x-4) = x/(x-2)
6x+x=7x
Simple,its just like this: 6x+1+7-3 =6x+8-3 =6x+5
6x+x = 7x
