Question

B) ſ 3x +2y=5,1 - 5.0 +2y=45;​

Answer 1

Объяснение:

3x + 2y = 5,

y = 45/-3;

3x + 2y = 5,

y = -15;

3х + 2 * (-15) = 15,

у = -15;

3х - 30 = 15,

у = -15;

3х = 30 + 15,

у = -15;

3х = 45,

у = -15;

y = 45/-3;

3x + 2y = 5,

y = -15;

3х + 2 * (-15) = 15,

у = -15;

3х - 30 = 15,

у = -15;

3х = 30 + 15,

у = -15;

3х = 45,

у = -15;

х = 15,

у = -15.

у = -15.

Ответ: (15, -15).
