Question

Es de método de igualación ocupó el procedimiento

Answer 1

6X - 18Y = -85 (1)

24X - 5Y = -5 (2)

6X = 18Y - 85

X = 3Y - 85/6

24X - 5Y = -5

24X = -5 + 5Y

X = -5/24 + 5Y/24.

X = X

3Y - 85/6 = -5/24 + 5Y/24

3Y - 5Y/24 = -5/24 + 85/6: Paso todo a venticuatroavos

(72Y/24) - (5Y/24) = -5/24 + 340/24

67Y/24 = 335/24:  Cancelo el 24,

67Y = 335

Y = 335/67

Y = 5.

Reemplazo el Valor de Y en (1)

6X - 18Y = -85

6X = -85 + 18Y

6X = -85 + 18(5)

6X = 90 - 85

6X = 5

X = 5/6

Rta: X = 5/6;  Y = 5
