The expression -10x - x can be simplified by combining like terms. Since both terms involve x, you can combine them to get -11x. Thus, -10x - x simplifies to -11x.
11x = 10x-19 Subtact 10x fromboth sides:- x = -19

To determine what must be added to (11x + 2y) to produce (10x - 4y), we can set up the equation: [ 11x + 2y + k = 10x - 4y ] Subtracting (11x + 2y) from both sides gives: [ k = 10x - 4y - 11x - 2y = -x - 6y ] Thus, (-x - 6y) must be added to (11x + 2y) to produce (10x - 4y).
-11x-1 = -10x-8 -11x+10 = -8+1 -1x = -7 x = 7

-10x = x-33 -10x-x = -33 -11x = -33 x = 11
10x-7+x+7 = 11x
6.10 is the solution to the equation 10x (6.11x) 6.
To simplify the expression (-3x + 4x + 5(2x + 1)), first combine like terms: (-3x + 4x = x). Next, distribute the 5: (5(2x) + 5(1) = 10x + 5). Now combine (x + 10x + 5) to get (11x + 5). Thus, the simplified expression is (11x + 5).
Add -x -6y. Just like with numbers, subtract the first from the second to find what to add to the first to get the second; keeping like terms together: (10x - 4y) - (11x + 2y) = (10x - 11x) + (-4y - 2y) = (10 - 11)x + (-4 - 2)y = -x - 6y
To simplify the expression (3x + 4(2x + 5)), first distribute the 4: [ 3x + 8x + 20 = 11x + 20. ] Now, simplify the second expression (6x + 5x + 5): [ 11x + 5. ] Since (11x + 20) is not equal to (11x + 5), Lauren is incorrect; the two expressions are not equivalent.
