2) -7x + 2=3x - 1;3) 10 - 2x = 12 + x​

Answer 1

Ответ:

Объяснение:

2) -7x + 2=3x - 1;

-7х-3х=-1-2

-10х=-3

Х=-3:(-10)

Х=0,3

3) 10 - 2x = 12 + x​

-2х-х=12-10

-3х=2

Х=-2/3

Answer 2

It seems like you've provided two equations. To assist you, I can solve these equations for the variable "x."

Equation 1: -7x + 2 = 3x - 1

Let's solve for x:

1. Add 7x to both sides to isolate the x terms on one side: 2 + 7x = 3x - 1 + 7x 7x + 2 = 10x - 1

2. Add 1 to both sides: 7x + 2 + 1 = 10x - 1 + 1 7x + 3 = 10x

3. Subtract 7x from both sides: 7x - 7x + 3 = 10x - 7x 3 = 3x

4. Divide both sides by 3 to solve for x: x = 3/3 x = 1

So, the solution for Equation 1 is x = 1.

Equation 2: 10 - 2x = 12 + x

Let's solve for x:

1. Subtract x from both sides to isolate the x terms on one side: 10 - 2x - x = 12 + x - x 10 - 3x = 12

2. Subtract 10 from both sides: 10 - 10 - 3x = 12 - 10 -3x = 2

3. Divide both sides by -3 to solve for x: x = 2 / -3 x = -2/3

So, the solution for Equation 2 is x = -2/3.

To summarize:

• Solution for Equation 1: x = 1
• Solution for Equation 2: x = -2/3
