Answer 1

А) 24-3x=2-x
-3x+x=2-24
-2x=-22
x=11

б) 6x-7x+12=0,5-x
-x+12=0,5-x
12=0,5
x€ O

Answer 2

Equation A: 3(8-x) = x-2

To solve equation A, we will simplify and isolate the variable x.

Starting with the equation: 3(8-x) = x-2

First, distribute the 3 on the left side: 24 - 3x = x - 2

Next, move all the terms with x to one side and the constant terms to the other side: 24 + 2 = x + 3x

Combine like terms: 26 = 4x

Finally, divide both sides by 4 to solve for x: x = 26/4 = 6.5

Therefore, the solution to equation A is x = 6.5.

Equation B: 6x - (7x - 12) = 0.5 - x

To solve equation B, we will simplify and isolate the variable x.

Starting with the equation: 6x - (7x - 12) = 0.5 - x

First, distribute the negative sign inside the parentheses: 6x - 7x + 12 = 0.5 - x

Next, combine like terms on both sides: -x + 12 = 0.5 - x

Now, add x to both sides to eliminate the variable on the left side: -x + x + 12 = 0.5 - x + x

Simplifying further, we have: 12 = 0.5

However, this equation is not possible since 12 does not equal 0.5.

Therefore, equation B has no solution.

To summarize: - Equation A: x = 6.5 - Equation B: No solution
