Question

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

Answer 1

Ответ:

8х-5=9+х

8х-х=9+5

7х=14

х=14:7

х=2

4(х-1)-3(х+2)=6

4х-4-3х-6=6

4х-3х=6+6+4

1х=16

Х=16:1

Х=16

Answer 2

It looks like you've provided two linear equations. Let's solve them step by step:

Equation 1: 8x - 5 = 9 + x

First, let's simplify the equation by subtracting 'x' from both sides: 7x - 5 = 9

Now, add 5 to both sides: 7x = 14

Finally, divide both sides by 7 to solve for 'x': x = 2

So, the solution for the first equation is x = 2.

Equation 2: 4(x - 1) - 3(x + 2) = 6

Distribute the constants inside the parentheses: 4x - 4 - 3x - 6 = 6

Combine like terms on both sides of the equation: 4x - 3x - 4 - 6 = 6 x - 10 = 6

Add 10 to both sides: x = 16

The solution for the second equation is x = 16.

To recap:

• Solution for the first equation (8x - 5 = 9 + x) is x = 2.
• Solution for the second equation (4(x - 1) - 3(x + 2) = 6) is x = 16.
