2*3a-2*8

6a-16

3*(2a-1)8*(3a-2)

6a-3+24a-16

30a-19

Пошаговое объяснение:

Answer 2

Let's solve each expression step by step:

1. 2×(3a-8) = 6a-16

To simplify this expression, we'll apply the distributive property of multiplication over addition/subtraction:

2×3a - 2×8 = 6a - 16

6a - 16 = 6a - 16

The equation is an identity, meaning the left side is equal to the right side for all values of 'a.' Therefore, the solution to this equation is all real numbers.

2. 3×(2a-1) + 8×(3a-2)

Again, we'll use the distributive property to simplify this expression:

3×2a - 3×1 + 8×3a - 8×2

6a - 3 + 24a - 16

Combine like terms:

(6a + 24a) + (-3 - 16)

30a - 19

Therefore, the simplified expression is 30a - 19.
