Question

2х-5+(3х-12) -4х+16-(4х-15) 4х-18+(-9-5х) 18+х-(-14+6х)

Answer 1

2х-5+(3х-12)=2х-5+3х-12=5х-17

-4х+16-(4х-15)=-4х+16-4х+15=-8х+31

4х-18+(-9-5х)=4х-18-9-5х=-х-27
18+х-(-14+6х)=18х+х+14-6х=13х+14

Answer 2

Let's simplify each expression step by step:

1. 2x - 5 + (3x - 12): Start by simplifying the expression within the parentheses: 2x - 5 + 3x - 12 Combine like terms: (2x + 3x) + (-5 - 12) 5x - 17

2. -4x + 16 - (4x - 15): Distribute the negative sign to the terms within the parentheses: -4x + 16 - 4x + 15 Combine like terms: (-4x - 4x) + (16 + 15) -8x + 31

3. 4x - 18 + (-9 - 5x): Simplify the expression within the parentheses: 4x - 18 + (-9 - 5x) Combine like terms: 4x - 18 - 9 - 5x (4x - 5x) + (-18 - 9) -x - 27

4. 18 + x - (-14 + 6x): Simplify the expression within the parentheses: 18 + x - (-14 + 6x) Distribute the negative sign: 18 + x + 14 - 6x Combine like terms: (x - 6x) + (18 + 14) -5x + 32

Therefore, the simplified expressions are:

1. 2x - 5 + (3x - 12) = 5x - 17
2. -4x + 16 - (4x - 15) = -8x + 31
3. 4x - 18 + (-9 - 5x) = -x - 27
4. 18 + x - (-14 + 6x) = -5x + 32
