Question

1)3*(2x+5)-(4x-17)=02) 6*(9-2x)+7*(4x*3)​​

Answer 1

Ответ:

1)6x+15-4x+17=0

6x-4x=-17-15

2x=-32

x=-16

2)54-12x+84x=0.

-12x=-84-54

-12x=-138

x=11,5

(Если без равенства 0, то 54+72x)

Пошаговое объяснение:

Answer 2

Let's solve both of these equations step by step:

1. 3*(2x+5)-(4x-17) = 0

First, distribute the 3 on the left side of the equation:

6x + 15 - (4x - 17) = 0

Now, remove the parentheses by distributing the negative sign inside the parentheses on the right side:

6x + 15 - 4x + 17 = 0

Combine like terms:

(6x - 4x) + (15 + 17) = 0

2x + 32 = 0

Now, isolate the variable x:

2x = -32

Divide both sides by 2:

x = -32 / 2

x = -16

So, the solution to the first equation is x = -16.

2. 6*(9-2x) + 7*(4x*3)

First, simplify each term separately:

6*(9-2x) = 54 - 12x 7*(4x*3) = 84x

Now, combine these two simplified terms:

54 - 12x + 84x

Combine like terms:

(84x - 12x) + 54

72x + 54

So, the simplified expression is 72x + 54.
