Answer 2

Sure, I'd be happy to help you solve these equations step by step.

Equation Р: 8x + 4(2 - 5x) = 13

Let's start by distributing the 4: 8x + 8 - 20x = 13

Now, combine like terms: -12x + 8 = 13

Subtract 8 from both sides: -12x = 5

Finally, divide by -12: x = -5/12

Equation С: -3(15 - 8x) + 2 - 11x = 7x - 18

Distribute the -3: -45 + 24x + 2 - 11x = 7x - 18

Combine like terms on both sides: 13x - 43 = 7x - 18

Subtract 7x from both sides: 6x - 43 = -18

Add 43 to both sides: 6x = 25

Divide by 6: x = 25/6

Equation Т: 18x - (15x + 4) = 11

First, simplify the expression within the parentheses: 18x - 15x - 4 = 11

Combine like terms: 3x - 4 = 11

Add 4 to both sides: 3x = 15

Divide by 3: x = 5

So, the solutions for the equations are: Equation Р: x = -5/12 Equation С: x = 25/6 Equation Т: x = 5
