Answer 1

Penjelasan dengan langkah-langkah:

3x - 2y = 3 |×2|6x - 4y = 6

2x + 2y = 4|×3|6x + 6y = 12

__________ _

-10y = -6

y = 0,6

2x + 2y = 4

2x + 2 (0,6) = 4

2x = 4 - 1,2

2x = 2,8

x = 28/10 × 1/2 = 28/20 = 1,4

(x + y)^3

= (1,4+0,6)^3

= 2^3

= 8

Answer 2

Jawaban:

(x + y)³ = 8

Penjelasan dengan langkah-langkah:

2x + 2y = 4

2(x + y) = 4

x + y = 4 ÷ 2

x + y = 2

(x + y)³ = 2³

(x + y)³ = 8
