-5x + 4x = -6 Combining like terms: -x = -6 Multiplying by -1 (or switching signs): x = 6

-1x-4-4x= -5x-4so it is -5x-4 -5x - 4this is done by combining like terms.

Collecting like terms they are equal to: 2x+6y

We can simplify this expression by combining the like terms. Here the likes terms are the z's and the x's.2z + 3z + 5z = 10z. (If we have 2 of something and add three of the same thing and then 5 of the same thing we will end up with 10 of that thing).Likewise we can combine the x's.6x - 2x = 4x. (You could think of this as 6x + - 2x if this helps with the idea of "combining".)Therefore we are able to simplify this expression as:2z + 3z + 5z + 4 + 6x - 2x = 10z + 4 + 4x.

6x + 14 = 20 + 4x ------ Combine like terms (subtract 4x and 14 from both sides). 2x = 6 --------------------- Divide by 2. x = 3

collect like terms and you get 4x + 5x + 8 - 3 ie 9x +5

3x + x = 4x

-1

no,, to be like term they must have the same variable,, such as 4x and 9x.. or 1y and 300y...

4y + 3w + 4x + 9y + 7x - 7w (combine like terms)-4w + 11x + 13y

Combine like terms, meaning add 12X plus 4X which is 16X and then you add 25Y plus 15Y which equals 40Y so the answer will be 16x+40y. combine like terms means add the ones with the same variable.

x+5+3x-7+9x+3-4x Collect like terms: 9x+1

It looks like you have 2 simultaneous equations with 2 variables:4x + 8y = 20 and -4x + 2y = -30. Solution is {x=7, y = -1}.One way to solve:Add the two equations together, combining like terms: (4x - 4x) + (8y + 2y) = 20-30 --> 0 + 10y = -10 --> y = -1. Substitute this into either of the original equations and solve for x=7, then check in the other equation to make sure you calculated correctly.
