Question

5(x-3)-3(1-x)-x-3 4(x+1)-(5-x)-x-3

Answer 1

5(х-3)-3(1-х)-х-3=5х-15-3+3х-х-3=7х-21
4(х+1)-(5-х)-х-3=4х+4-5+х-х-3=4х-4

Answer 2

5х-15-3+Зх-х-3=7х-21
4х+4-5+х-х-3=4х-4

Answer 3

To simplify the given expressions, let's solve them step by step:

1. 5(x-3) - 3(1-x) - x - 3

First, apply the distributive property:

= 5x - 15 - 3 + 3x - x - 3

Combine like terms:

= 5x + 3x - x - 15 - 3 - 3

Combine the x terms:

= (5x + 3x - x) - 15 - 3 - 3

= 7x - 21

So, the simplified form of the expression is 7x - 21.

2. 4(x+1) - (5-x) - x - 3

Again, apply the distributive property:

= 4x + 4 - 5 + x - x - 3

Combine like terms:

= 4x + x - x + 4 - 5 - 3

Combine the x terms:

= (4x + x - x) + 4 - 5 - 3

= 4x - 4

So, the simplified form of the expression is 4x - 4.
