Question

3x+2+3x+3=23 3×x+1+3x+1=30 4x+6+12+2×(x+1)

Answer 1

3x+2+3x+3=23

3х+3х=23-3-2

6х=18

Х=18:6

Х=3

3×x+1+3x+1=30

3х+3х=30-1-1

6х=28

Х=28:6

Х=4 2/3

4x+6+12+2×(x+1)=98

4х+6+12+2х+2=98

4х+2х=98-6-2-12

6х=78

Х=78:6

Х=13

Answer 2

Let's solve each equation step by step:

1. 3x + 2 + 3x + 3 = 23

Combine like terms: 6x + 5 = 23

Now, isolate the variable (x) on one side of the equation: 6x = 23 - 5 6x = 18

Finally, solve for x: x = 18 / 6 x = 3

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

2. 3×x + 1 + 3x + 1 = 30

Combine like terms: 6x + 2 = 30

Now, isolate the variable (x) on one side of the equation: 6x = 30 - 2 6x = 28

Finally, solve for x: x = 28 / 6 x = 4.67 (rounded to two decimal places)

So the solution to the second equation is x ≈ 4.67.

3. 4x + 6 + 12 + 2×(x + 1)

Simplify the expression inside the parentheses: 4x + 6 + 12 + 2x + 2

Combine like terms: (4x + 2x) + (6 + 12 + 2)

Now, combine further: 6x + 20

The expression 4x + 6 + 12 + 2×(x + 1) simplifies to 6x + 20.

However, there is no equal sign (=) or another expression on the right side, so this is not an equation to solve. If you have an equation or specific value you want to find for x, please provide that information, and I'll be happy to assist further.
