AysviL [449]3 years ago
4 0

Step-by-step explanation:

37x + 41y = 70 --- R¹

41x + 37y = 86 --- R²

R¹ + R² : 78x + 78y = 156

78(x + y) = 156

x + y = 2 --- R³

R¹ - R² : -4x + 4y = -16

4(y - x) = -16

y - x = -4 --- R⁴

R³ + R⁴ : 2y = -2

y = -1

R³ - R⁴ : -2x = -6

x = 3

Nikolay [14]

Answer:

y=-3/13x-89/13

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-8)-(-5)/5-(-8)

m=-3/13

y-y=m(x-x1)

y-(-8)=-3/13(x-5)

y+8= -3/13x+15/13

-8 -8

y=-3/13x-89/13
