    Step-by-step explanation:

    1. 2 (x+3) + 3 (5-x) =

    Simplifying

    2 (x + 3) + 3 (5 + - 1x) = 0

    Reorder the terms:

    2 (3 + x) + 3 (5 + - 1x) = 0

    (3 * 2 + x * 2) + 3 (5 + - 1x) = 0

    (6 + 2x) + 3 (5 + - 1x) = 0

    6 + 2x + (5 * 3 + - 1x * 3) = 0

    6 + 2x + (15 + - 3x) = 0

    Reorder the terms:

    6 + 15 + 2x + - 3x = 0

    Combine like terms: 6 + 15 = 21

    21 + 2x + - 3x = 0

    Combine like terms: 2x + - 3x = - 1x

    21 + - 1x = 0

    Solving

    21 + - 1x = 0

    Solving for variable 'x'.

    Move all terms containing x to the left, all other terms to the right.

    Add '-21' to each side of the equation.

    21 + - 21 + - 1x = 0 + - 21

    Combine like terms: 21 + - 21 = 0

    0 + - 1x = 0 + - 21

    -1x = 0 + - 21

    Combine like terms: 0 + - 21 = - 21

    -1x = - 21

    Divide each side by '-1'.

    x = 21

    Simplifying

    x = 21

    2. 3 (y+2) - 4y=-24y

    Simplifying

    3 (y + 2) + - 4y = - 24y

    Reorder the terms:

    3 (2 + y) + - 4y = - 24y

    (2 * 3 + y * 3) + - 4y = - 24y

    (6 + 3y) + - 4y = - 24y

    Combine like terms: 3y + - 4y = - 1y

    6 + - 1y = - 24y

    Solving

    6 + - 1y = - 24y

    Solving for variable 'y'.

    Move all terms containing y to the left, all other terms to the right.

    Add '24y' to each side of the equation.

    6 + - 1y + 24y = - 24y + 24y

    Combine like terms: - 1y + 24y = 23y

    6 + 23y = - 24y + 24y

    Combine like terms: - 24y + 24y = 0

    6 + 23y = 0

    Add '-6' to each side of the equation.

    6 + - 6 + 23y = 0 + - 6

    Combine like terms: 6 + - 6 = 0

    0 + 23y = 0 + - 6

    23y = 0 + - 6

    Combine like terms: 0 + - 6 = - 6

    23y = - 6

    Divide each side by '23'.

    y = - 0.2608695652

    Simplifying

    y = - 0.2608695652

    3. - (x+2) - 2 (1-x) =

    Simplifying

    -1 (x + 2) + - 2 (1 + - 1x) = 0

    Reorder the terms:

    -1 (2 + x) + - 2 (1 + - 1x) = 0

    (2 * - 1 + x * - 1) + - 2 (1 + - 1x) = 0

    (-2 + - 1x) + - 2 (1 + - 1x) = 0

    -2 + - 1x + (1 * - 2 + - 1x * - 2) = 0

    -2 + - 1x + (-2 + 2x) = 0

    Reorder the terms:

    -2 + - 2 + - 1x + 2x = 0

    Combine like terms: - 2 + - 2 = - 4

    -4 + - 1x + 2x = 0

    Combine like terms: - 1x + 2x = 1x

    -4 + 1x = 0

    Solving

    -4 + 1x = 0

    Solving for variable 'x'.

    Move all terms containing x to the left, all other terms to the right.

    Add '4' to each side of the equation.

    -4 + 4 + 1x = 0 + 4

    Combine like terms: - 4 + 4 = 0

    0 + 1x = 0 + 4

    1x = 0 + 4

    Combine like terms: 0 + 4 = 4

    1x = 4

    Divide each side by '1'.

    x = 4

    Simplifying

    x = 4

    4. whats? is the equation
