Question

6x-3×(2y-(y-(1-4y))) Если 2x + 3y = 5

Answer 1

Ответ:

Объяснение:

2х=5-3y

15-9y-6y+3y+3+12y=0

-3y=-18

y=6

x=-6.5

Answer 2

To simplify the expression $6x - 3 \times (2y - (y - (1 - 4y)))$ given that $2x + 3y = 5$, we first need to perform the operations inside the parentheses and then simplify the resulting expression.

Step 1: Simplify the expression inside the innermost parentheses:

$2y - (y - (1 - 4y))$

To remove the innermost parentheses, distribute the negative sign:

$2y - y + 1 - 4y$

Combine like terms:

$-3y + 1$

Step 2: Substitute $2x + 3y$ with $5$ (given condition):

$6x - 3 \times (-3y + 1)$

Step 3: Continue simplifying:

Distribute the $-3$ to $-3y + 1$:

$6x + 9y - 3$

That's the simplified expression for $6x - 3 \times (2y - (y - (1 - 4y)))$ under the condition $2x + 3y = 5$.
