Question

Afla valoarea lui,a din expresia 57 - 8 X 3+2 x (10 - 6) + ax 3 = 50.​

Answer 1

$57 - 8 \times 3 + 2 \times (10 - 6) + a \times 3 = 50 \\ \\ 57 - 24 + 2 \times 4 + a \times 3 = 50 \\ \\ 57 - 24 + 8 + a \times 3 = 50 \\ \\ 33 + 8 + a \times 3 = 50 \\ \\ 41 + 3a = 50 \\ \\ 3a = 50 - 41 \\ \\ 3a = 9 \\ \\ a = 9 \div 3 \\ \\ a = 3$

ღSalutare!ღ

57-8×3+2×(10-6)+a×3=50

57-24+2×4+a×3=50

33+8+a×3=50

41+a×3=50

a×3=50-41

a×3=9

a=9:3

a=3✅
