Answer 2

Simplifying Expressions

Let's simplify the given expressions step by step:

a) 0.5a + 3b - 4c = b

To simplify this expression, we can start by moving all the terms involving 'a' to one side and all the terms without 'a' to the other side:

0.5a - b = 4c - 3b

b) 2.6 - (±k + 1) = c

Here, we have an expression involving 'c' and 'k'. To simplify it, we can remove the parentheses and combine like terms:

2.6 ± k - 1 = c

Simplifying further, we get:

1.6 ± k = c

c) 1.3a - (2 + 4.6a) = 0

To simplify this expression, we can remove the parentheses and combine like terms:

1.3a - 2 - 4.6a = 0

Simplifying further, we get:

-3.3a - 2 = 0

d) 6x - 3 + x - 7 = 0

To simplify this expression, we can combine like terms:

7x - 10 = 0

e) 3x + y - (-x - 4y) = 0

To simplify this expression, we can remove the parentheses and combine like terms:

3x + y + x + 4y = 0

Simplifying further, we get:

4x + 5y = 0

These are the simplified forms of the given expressions.
