Question

(17а-6в)+4(-5а+4в)=-3а+10в​

Answer 1

Объяснение:

17a-6b-20a+16b=-3a+10b

17a-17a=0b

0a=0b

=> a-любое число

    b-любое число

a∈R   b∈R

Answer 2

Let's simplify the expression step by step:

(17a - 6b) + 4(-5a + 4b)

Distribute the 4 to each term inside the parentheses:

17a - 6b + 4 * -5a + 4 * 4b

Multiply:

17a - 6b - 20a + 16b

Combine like terms:

(17a - 20a) + (-6b + 16b)

-3a + 10b

Therefore, the simplified expression is -3a + 10b, not -3a + 10v.
