Answer 2

It appears that you've provided a set of equations. Let's solve each of them step by step:

1. 5(х+3) = 2х - 3х + 7 Start by distributing the 5 on the left side of the equation: 5x + 15 = -x + 7 Now, move the -x and 15 to the right side of the equation: 5x + x = 7 - 15 Combine like terms: 6x = -8 Divide by 6: x = -8/6, which simplifies to x = -4/3.

2. 4(х-2) = 2×(х-3) Start by distributing on both sides of the equation: 4x - 8 = 2x - 6 Now, move the 2x and -8 to the right side of the equation: 4x - 2x = -6 + 8 Combine like terms: 2x = 2 Divide by 2: x = 2/2, which simplifies to x = 1.

3. 5a/6 - (2a+1) = 0 Start by simplifying the expression inside the parentheses: 5a/6 - 2a - 1 = 0 Now, add 2a and 1 to both sides of the equation to isolate the variable: 5a/6 = 2a + 1 Next, multiply both sides by 6 to get rid of the fraction: 5a = 12a + 6 Now, move 12a to the left side of the equation by subtracting it from both sides: 5a - 12a = 6 Combine like terms: -7a = 6 Finally, divide by -7 to solve for a: a = 6 / (-7), which simplifies to a = -6/7.

4. 6 + 4 × (2-х) = 3 - 5х Start by simplifying both sides of the equation: 6 + 8 - 4x = 3 - 5x Combine like terms: 14 - 4x = 3 - 5x Now, add 5x to both sides to isolate the variable: 14 + x = 3 Subtract 14 from both sides to solve for x: x = 3 - 14 x = -11.

These are the solutions for the equations you provided.
