Question

1)-3(x-1)=24-10x 2)2(4x+5)-3(x+6)=9x+8

Answer 1

Ответ:

x=3; x=-4

Пошаговое объяснение:

-3(x-1)=24-10x

-3x+3=24-10x

-3x+10x=24-3

7x=21

x=3

2(4x+5)-3(x+6)=9x+8

8x+10-3x-18=9x+8

8x-3x-9x=8-10+18

-4x=16

x=-4

Answer 2

Let's solve each equation step by step:

1. -3(x - 1) = 24 - 10x

First, distribute the -3 on the left side: -3x + 3 = 24 - 10x

Next, move all the x terms to one side and the constant terms to the other side: -3x + 10x = 24 - 3 7x = 21

Finally, solve for x by dividing both sides by 7: x = 21 / 7 x = 3

So the solution for the first equation is x = 3.

2. 2(4x + 5) - 3(x + 6) = 9x + 8

First, distribute the coefficients on the left side: 8x + 10 - 3x - 18 = 9x + 8

Next, combine like terms: (8x - 3x) + (10 - 18) = 9x + 8 5x - 8 = 9x + 8

Now, move all the x terms to one side and the constant terms to the other side: 5x - 9x = 8 + 8 -4x = 16

Finally, solve for x by dividing both sides by -4: x = 16 / -4 x = -4

So the solution for the second equation is x = -4.
