Question

x-(2-5x)

Answer 1

x-(2-5x)

Answer 2

x-2+5x
6x-2

Answer 3

Thank you but can you explain the steps?

Answer 4

whenever you have negative outside of a parenthesis , change sign inside the parenthesis

Answer 5

Just some example
-(a+b)= -a-b
-(a-b)=-a+b

Answer 6

Think of it as multiplying the terms in the bracket by a -1.

-1 * 2 = -2
-1 * -5x = 5x

Answer 7

o.k making more sense

Answer 8

This is called the distributive property of multiplication. Sometimes some simpler numbers make it easier to see. For example,

5(8+2) = 5*8 + 5*2
Either way you work it out, you still get the same answer, but the second version is useful in algebra, of course.

Answer 9

Still not completely understanding. Can someone show step by step

Answer 10

The only confusing part about your example is that you have x - (2-5x).

The coefficient before the brackets/parentheses is assumed to be a 1, so it really is:

x-1(2-5x)

You have to use the distributive property to multiply the terms in the brackets by -1.

x + (-1)(2) + (-1)(-5x)
x + (-2) + 5x
x-2+5x and grouping the like x terms
6x - 2
