Question

Даю 10 при каком значений неизвестной:значения выражений 4(6-4y) и 5(7-3y)-19 равны ? ПЖ

Answer 1

$4(6-4y)=5(7-3y)-19;\\24-16y=35-15y-19;\\y=24+19-35;\\y=8.$

Ответ: при $y=8.$

Answer 2

Solving for the Unknown Value in the Given Expressions

To find the value of the unknown variable, let's set the expressions 4(6-4y) and 5(7-3y)-19 equal to each other and solve for y.

The given expressions are: 1. 4(6-4y) 2. 5(7-3y)-19

Setting them equal to each other: 4(6-4y) = 5(7-3y)-19

Now, let's solve for y.

Solution:

Step 1: Expand and simplify the expressions: - 4(6-4y) = 24 - 16y - 5(7-3y)-19 = 35 - 15y - 19 = 16 - 15y

Step 2: Set the expressions equal to each other and solve for y: 24 - 16y = 16 - 15y 24 - 16y + 15y = 16 24 - y = 16 -y = 16 - 24 -y = -8 y = 8

Conclusion:

The value of the unknown variable is y = 8.
