"di rumah di omelin, di luar rumah di cariin" trus aku harus apa? ;_;

4x + 4y × 5x - 5y

x = 2
y = 5

4x + 4y × 5x - 5y

= 4x + 20xy - 5y

= 4(2) + 20(2)(5) - 5(5)

= 8 + 20(10) - 25

= 8 + 200 - 25

= 208 - 25

= 183

$\sf 4x + 4y × 5x - 5y$

$\sf = 4(2) + 4(5) × 5(2) - 5(5)$

$\sf = ( 4 \times 2) + (4 \times 5) × (5 \times 2) - (5 \times 5)$

$\sf = 8+ (4 \times 5) × (5 \times 2) - (5 \times 5)$

$\sf = 8+ 20 × (5 \times 2) - (5 \times 5)$

$\sf = 8+ 20 × 10 - (5 \times 5)$

$\sf = 8+ 20 × 10 - 25$

$\sf = 8+ (20 × 10) - 25$

$\sf = 8+ 200 - 25$

$\sf =208 - 25$

$\sf =183$
