(3y+8-[-15+6y-(-3y+2)-(5y+4)]-29}=-5
respuesta y procedimiento

Answer 1

Respuesta:

Reorder the terms:

-1(3y + 8 + -1(-15 + 6y + -1(2 + -3y) + -1(5y + 4)) + -29) = -5

-1(3y + 8 + -1(-15 + 6y + (2 * -1 + -3y * -1) + -1(5y + 4)) + -29) = -5

-1(3y + 8 + -1(-15 + 6y + (-2 + 3y) + -1(5y + 4)) + -29) = -5

Reorder the terms:

-1(3y + 8 + -1(-15 + 6y + -2 + 3y + -1(4 + 5y)) + -29) = -5

-1(3y + 8 + -1(-15 + 6y + -2 + 3y + (4 * -1 + 5y * -1)) + -29) = -5

-1(3y + 8 + -1(-15 + 6y + -2 + 3y + (-4 + -5y)) + -29) = -5

Reorder the terms:

-1(3y + 8 + -1(-15 + -2 + -4 + 6y + 3y + -5y) + -29) = -5

Combine like terms: -15 + -2 = -17

-1(3y + 8 + -1(-17 + -4 + 6y + 3y + -5y) + -29) = -5

Combine like terms: -17 + -4 = -21

-1(3y + 8 + -1(-21 + 6y + 3y + -5y) + -29) = -5

Combine like terms: 6y + 3y = 9y

-1(3y + 8 + -1(-21 + 9y + -5y) + -29) = -5

Combine like terms: 9y + -5y = 4y

-1(3y + 8 + -1(-21 + 4y) + -29) = -5

-1(3y + 8 + (-21 * -1 + 4y * -1) + -29) = -5

-1(3y + 8 + (21 + -4y) + -29) = -5

Reorder the terms:

-1(8 + 21 + -29 + 3y + -4y) = -5

Combine like terms: 8 + 21 = 29

-1(29 + -29 + 3y + -4y) = -5

Combine like terms: 29 + -29 = 0

-1(0 + 3y + -4y) = -5

-1(3y + -4y) = -5

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

-1(-1y) = -5

Remove parenthesis around (-1y)

-1 * -1y = -5

Multiply -1 * -1

1y = -5

Solving

1y = -5

Solving for variable 'y'.

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

Divide each side by '1'.

y = -5

Simplifying

y = -5
