Answer 1

1) 3х+4+2х+3=-7х+12

3х+2х+7х=12-3-4

12х=5

х=5/12

2) 8-15+11х=5х+3-7х-4

11х-5х+7х=3-4+15-8

13х=6

х=6/13

3) 3+4х-11-10х=7+13-4

4х-10х=16+11-3

-6х=24

х=-4

4) 15х-10=3х+1-2х-4

15х-3х+2х=1-4+10

14х=7

х=1/2=0,5

Answer 2

1) (3x+4)+(2x+3)=-7x+12

To solve the equation (3x+4)+(2x+3)=-7x+12, we can simplify the left side of the equation by combining like terms:

(3x+4)+(2x+3) = 5x + 7

Now, the equation becomes:

5x + 7 = -7x + 12

To solve for x, we can isolate the variable on one side of the equation. Let's move the -7x term to the left side by adding 7x to both sides:

5x + 7 + 7x = -7x + 7x + 12

Combining like terms, we get:

12x + 7 = 12

Next, let's move the constant term to the right side by subtracting 7 from both sides:

12x + 7 - 7 = 12 - 7

Simplifying further, we have:

12x = 5

Finally, to solve for x, we divide both sides of the equation by 12:

12x/12 = 5/12

x = 5/12

Therefore, the solution to the equation (3x+4)+(2x+3)=-7x+12 is x = 5/12.
